    Evaluating human capital: an exploratory

    study of management practice

    The article explores the development of systems of human capital evaluation in a

    number of large UK firms. Human capital is a much used term in business literature,

    and it is widely recognised that firms need to develop mechanisms to determine the

    value of their employee base. An extensive human capital literature has developed in

    which the authors propose elaborate systems for measuring a firms human assets. Thisarticle does not seek to offer yet another human capital model. Rather, the aim is to

    examine the management practices through which human capital evaluation is

    undertaken. The article is based on an exploratory study of such practices in 11 major

    firms in the UK. The findings are highlighted as follows. First, we note the preference

    for internal over external (static accountancy-based) reporting. Secondly, we highlight

    the diverse nature of human capital evaluation systems that exist across UK business.

    Thirdly, we explore the relationship between practices of evaluation and the role and

    position of the HR function within the firm. Finally, in conclusion, we address the

    implications of the human capital perspective for practitioners, arguing that there is no

    single formula that can be applied to its evaluation. We go on to suggest that the

    importance of the human capital concept and its measurement may lie in its ability to

    re-frame perceptions of the relationship between the contribution of employees and the

    competitive performance of the business.

    The recognition that much of the added value created by firms is becoming more

    dependent on assets other than physical capital has stimulated a vast literature

    in the area of intellectual capital and intangible assets (Berkowitz, 2001; Drake,

    1998; Leadbeater, 2000; Mayo, 2001; Miller and Wurzburg, 1995; Roos et al, 1997; Sveiby,

    1997). In particular, emphasis has been placed on the importance of a companys

    human capital the value-creating skills, competencies, talents and abilities of its

    workforce as an essential component in gaining competitive advantage (Bontis and

    Dragonetti, 1999; Leadbeater, 2000). As a result, there have been calls for human assets

    to be incorporated into company accounts, thereby giving investors a much clearer

    picture of where company value lies (Drake, 1998). In the UK specifically, such calls

    notably from the professional body for personnel/HR managers, the CharteredInstitute of Personnel and Development (CIPD) have begun to exert an influence on

    government policy. In response, a UK government taskforce was established, and this

    has recently published its report, Accounting for people.1

    Approaches to human capital have been widely debated over the 40-year period

    since the concept was first popularised by studies of the role of education in economic

    development (Schultz, 1961) and within accountancy circles (Hermanson, 1964;

    Sackman et al, 1989). Views of human capital tend to revolve around a core

    Evaluating human capital: an exploratory study of management practice

    specification which is to do with employee competencies sometimes equated with

    knowledge together with the application of such competencies, often in the form of

    employee commitment (Ulrich, 1998). All of these writings agree that human capital issomething that employees bring to the organisation (and take with them when they

    leave), yet is also something that is developed within the workplace through training

    and work experience (Miller and Wurzburg, 1995: 17). From this wide and burgeoning

    literature, however, it is possible to identify several distinct schools of thought, which

    range in their interest from theory building to the development of tools. One important

    school of thought, for instance, is human resource accounting (HRA), which has

    existed at the margins of academic studies of accountancy for many years (Flamholtz,

    1999). Given the growing emphasis on people as key company assets in a knowledge-

    driven economy, HRA has become the subject of renewed interest (Roslender andDyson, 1992).

    A second school focuses on the non-standardised, tacit, dynamic and context-

    dependent features of human capital. Viewed from the perspective of competitive

    advantage, these features are seen as significant because they reinforce the causal

    ambiguity of human capital and hence its inimitability by competitors (Carpenter et al,

    2001). A third school, which has developed recently, focuses more narrowly on the

    competitive value of scarce and inimitable skills. Inspired by the notion of a war for

    talent (Haker, 2001; Michels et al, 2001), a number of writers have addressed questions

    of recruiting and retaining the most valued employees often technical specialists oryoung managers of high potential (Annunzio, 2001; Sadler and Milmer, 1993). This

    focus, however, has been rebutted by other writers (O'Reilly and Pfeffer, 2000; Pfeffer,

    2001), arguing that the value of human capital is context-dependent. In this view,

    concentrating managerial efforts on the recruitment and retention of talented

    individuals risks neglecting the development of the workforce as a whole.

    A fourth set of studies is explicitly tools and systems-orientated, and seeks to

    develop robust systems for measuring human capital (Becker et al, 2001; Davenport,

    1999; Fitz-Enz, 2000; LeBlanc et al, 2000; Mayo, 2001, 2002; Ulrich, 1998; Zwell and

    Ressler, 2000). Similarly, several major consultancy firms have developedmethodologies relating to human capital management as part of their product

    offerings. What these approaches have in common is that they all share a commitment

    to building robust metrics for measuring one of the most intangible of intangibles, and

    recognise that the development of such metrics will help firms and investors to

    understand the drivers of corporate performance, enabling firms to identify future

    sources of value in a competitive business environment.

    Despite their diversity in approach, a common strand of many of the existing

    schools is their concern with abstract and prescriptive models of human capital which

    are based on unitary and economistic views of business organisation. The rulingassumption in such studies is that improved information on managing human capital

    leads directly to improved performance (Becker et al, 2001: 13). Issues of the

    problematic relationship between information and decision-making (March and

    Simon, 1958), and the mediating role of management practice and systems (Guilln,

    2003), are somewhat neglected. In contrast, the principal contribution of this article is

    to provide an exploratory account of the actual development of systems of human

    capital evaluation at firm level. Our empirical study of such systems across a range of

    firms allows us to shed some light on the relationships between human capital

    evaluation and management practices within particular contexts. This study not onlyhighlights innovations in the methods employed by firms to evaluate human capital

    but also links these developments to management practices and the influence of

    particular sectoral contexts.

    EVALUATION OF HUMAN CAPITAL IN PRACTICE

    The gap between existing theories of human capital and its evaluation within

    particular contexts is a significant one. The features that are seen as critical to

    organisational performance include the flexibility and creativity of individuals, their

    ability to develop skills over time and to respond in a motivated way to different

    contexts (Davenport, 1999). Yet, many of these features depend on the acquisition and

    application of tacit knowledge (Lave and Wenger, 1991), and are thus not readily

    amenable to measurement and representation. This paradox poses a major challenge to

    systems designed to evaluate human capital in practice. Given evidence that there is

    unlikely to be a universal formula for measuring human capital (Mayo, 2002), it

    suggests that systems of evaluation and the way they are implemented in practice mayvary according to a number of different features of the organisational context.

    Based on a review of the existing literature on HR systems, our study identified a

    number of contextual features that were seen as likely to influence evaluation in

    practice. These features served to inform the development of our research questions as

    outlined below. First, existing work suggests that HR systems may be implemented

    with different types of objective, ranging from strategic objectives linked to the

    overall goals of the organisation, to operational objectives that are concerned with

    the efficiency of the HR function (Hendry, 1995; Storey, 1992; Tyson, 1995). The

    strategic label is a problematic one, of course, and needs to be understood as asocially constructed distinction within management practice (Scarbrough, 1997).

    However, within the parameters of our study, this distinction offered a useful

    shorthand means of identifying the kind of business objectives that were served by

    human capital evaluation.

    Secondly, HR systems are seen as varying significantly in their scope, depending on

    the status and numbers of employees they encompass (Keegan, 1998; Scarbrough,

    2000). This suggested that the scope of the evaluation system was an important

    question. Thirdly, a number of studies have highlighted the relationship between the

    implementation and effectiveness of HR systems and the role played by the HR

    function within the organisation (Guest et al; 2000; Legge, 1978). Fourthly, an

    important issue in the arena of accounting systems, though less well advanced in the

    human resource area, is the question of the audience for the reporting of information.

    Accounting systems are subject to a binary division between those that address an

    external audience (conventionally termed financial accounting) and those that

    generate information for internal use (labelled management accounting). In applying

    this distinction to human capital, we were keen to establish whether evaluation

    systems had been developed with an internal or an external audience in mind.

    In the remainder of this article, we will describe the findings of our study in relation

    to these initial questions, and will go on to explore their implications for the furtherdevelopment of management practice in future.

    RESEARCH METHODS

    Our study began with an initial review of the literature summarily outlined in the

    introduction which was designed to inform and contextualise our research

    questions. Subsequently, fieldwork based on comparative case study methods of

    Juanita Elias and Harry Scarbrough

    data-gathering was conducted over a six-month period. Although lacking the

    advantages of single-shot longitudinal studies (Pettigrew, 1985), such an approach

    does enable a comparative analysis based on within-group similarities and differences(Eisenhardt, 1989). Our selection criteria for the sample were threefold. First, we

    acknowledged the context-dependent nature of human capital by drawing cases from

    a range of different sectoral contexts. Secondly, given our concern with management

    practice, we sought to include firms that were understood from external reports or

    from personal contacts to be developing systems for the collection of data on human

    capital (although we acknowledge the potential bias towards more visible, larger

    corporations implicit in this approach). Thirdly, we sought to ensure that our cases

    reflected a range of workforce skill-sets, ranging from production line and front-line

    service skills to the different skills found in high-tech, knowledge-intensive andprofessional services firms.

    Within each firm in our sample, we sought to interview one or two respondents

    who were identified by senior managers as playing a key role in the development

    and implementation of their approach to human capital evaluation. A significant

    observation here was that in all instances the key respondents identified to us were

    either located within the mainstream HR function or within specialist units attached to

    that function a point to which we return later. Our final sample of 20 HR managers

    from 11 organisations included 11 director-level managers (see appendix for further

    details). The identities of the organisations involved have been protected bypseudonyms to respect their confidentiality.

    Given variations in the scope of initiatives, size of organisation and the access made

    available by the firm, the actual number of interviews varied from one firm to another.

    In each case, however, interviews lasted around one-and-a-half hours (often longer)

    and, with the exception of one telephone interview, were all conducted face to face. As

    befits an exploratory study, interviews were conducted on a semi-structured basis,

    revolving around a set of core themes based on our overall research questions.

    Interviews were taped and transcribed, and notes were returned to respondents to

    ensure the accuracy of our findings. Wherever possible, interview materials weresupplemented by extensive documentary evidence on existing management policies

    and practices in this area.

    As we noted above, there are many different interpretations of human capital

    available within the existing literature. To avoid a pre-emptively restrictive approach in

    this exploratory study, we adopted a broadly based definition of human capital which

    saw it as encompassing the whole range of value-creating skills, competencies, talents

    and attributes that employees bring to the firm. Moreover, since the term human

    capital was not itself in wide circulation among practitioners (although it has been

    more recently popularised by the government taskforce described earlier), thisdefinition helped us to operationalise the concept in relation to specific practices and

    systems for evaluating workforce competencies and attitudes. Interviews with

    managers often revealed some managerial resistance to the term human capital itself,

    which cloaked both normatively positive and negative views of its evaluation in

    practice. Thus, one manager commented:

    The term human capital is interesting. I wouldnt say that Im pursuing a

    human capital agenda But if we talk about competency and the value of

    competence in fulfilling our value proposition to our customer that I can

    talk about. Then one starts to talk about capital. But how one values thatcapital becomes a bit of a problem. Director of HR, CopyCo

    Conversely, another was more sceptical:

    In this company most assets are tangible. But people as an asset is not

    something that is easily measured. Its measured very easily as a cost

    because this is very simple to do. HR director, CarCo

    Despite these concerns about the terminology of human capital evaluation, what

    we did find was that many of the companies in our study possessed extensive systems

    for measuring and reporting on the knowledge and skills of their employees. These

    systems typically focused on competency-based definitions of such knowledge and

    skills based on normative assessments within specific organisational contexts

    (Sandberg, 1994).

    INTERNAL AND EXTERNAL REPORTING

    The call for more widespread reporting by organisations on the value of their humancapital has its origins in HRA. This radical accountancy approach put forward the

    idea that there was a need for constructing meaningful systems for the reporting of a

    firms human assets (and other intangible assets) alongside its physical and financial

    assets (Berkowitz, 2001; Roslender and Dyson, 1992). It should be acknowledged,

    however, that, unlike other intangibles, human capital has certain unique qualities

    that make valuation very difficult. The most important of these is that human capital

    is not really an asset at all, in the sense that it is something owned by the company

    people being free to move and withdraw their skills. Furthermore, as we have already

    highlighted, human capital is also difficult to measure because of its context-dependent nature.

    Given these problems, it is unsurprising that a preference for in-house reporting

    systems was noted in the fieldwork. The lack of external reporting by firms is partly to

    do with the problem associated with measurement, as well as there being no legal

    obligations for firms to report this information externally. It is also an indication of the

    relative lack of interest that the UK investor community (in common parlance, the

    City ie the City of London) has in all forms of intangible assets (Vance, 2001). An HR

    director of an insurance firm commented:

    The City is not really that interested. The City isnt even that interested inour brand, and brand is one of the more tangible intangibles It is only

    really interested in the impact on the bottom line and thats OK we as

    an organisation have to believe that service and morale are key to

    achieving profit long term. For me its not just about short-term or long-

    term focus they all enable you to deliver profit but youll only deliver

    sustainable profit if these other things are right.

    Director of HR projects, InsuranceCo

    A senior training manager at a telecommunications company, interviewed shortly

    after a meeting with City analysts, commented:

    Judging from some of the market analysts questions that Ive heard this

    morning, this says to me that they are a long way off from showing any

    kind of interest in that kind of information [on human capital] There

    were six or seven priorities that the CEO listed in terms of focus for our

    three-year strategy. One of them was motivating people. But there wasnt

    a single question on motivating people. All the questions were about

    what are the financial returns on this and that and the other, what is your

    Comments

    Company has outlined its approach to measuring and evaluating human capital for largelyoperational purposes, and this has been rolled out across the business following a major merger.There is growing appreciation of the strategic role of this information, and human capitalfeatures in strategic planning via the inclusion of measures of morale and customer services asa key company goal, alongside the more traditional financial focus of company planning. Themeasurement of employee competencies is broad in scope, although the company also hasconcerns about retaining certain key talented populations such as underwriters.

    Comprehensive approach to evaluating human capital across the whole of the business.Data has strategic value, especially in terms of building the companys commitment tocorporate social responsibility.

    Human capital evaluation does have a strategic focus, but this is more targeted around thegoal of delivering a learning organisation through training, development and knowledgemanagement programmes. However, there is no emphasis on metrics that would supportand measure progress towards this goal. Use of metrics for mainly operational purposes (egaudit skills of employees to ensure that they have sufficient staff to perform a specific task,or appraisal systems that use data on a very individualistic basis). Many initiatives are broadin scope, while others such as talent retention initiatives aimed at retaining highly technicalstaff are much more narrow in focus.

    Strong emphasis on accurately measuring business leader performance through a widerange of measurement tools (egpeer review, 360o appraisal, employee feedback, customersurveys). Measurement based on an identified range of leadership competencies andbehaviour. Leads to definite training and development outcomes aimed at building and

    retaining strategic and visionary leadership for the company.

    Little development in human capital evaluation aside from some limited changes to theappraisal system. The company is highly dependent on key talented individuals, and isincreasingly concerned about talent retention. However, the lack of any strategic approach todeveloping, recruiting and retaining talent, let alone systems in place to monitor andmeasure this process, means that talent retention practices are largely confined to increasedlevels of remuneration to high-flyers.

    An emphasis on measuring employee competencies in strategic planning (for example, canthe company develop a new product with the current level of competency in its workforce ata particular location?), and use of balanced scorecard further underlines this commitment tothe strategic importance of HRM.

    Approach is targeted on the top management group. Information generated on this group viaappraisal and employee feedback systems is key to targeting potential business leaders in aglobally organised company. Approach to evaluating human capital among this top leadershipgroup was specifically born out of concerns regarding the war for talent.

    Clear approach based on metrics. Use of a strategic unit within HR to undertake the processof human capital evaluation. Focus is broad; all employees are engaged in the process ofhuman capital evaluation.

    A new HR-directed unit is taking the lead in the development of metrics for evaluatinghuman capital. The process is very much in its early stages, but has clear strategic focus. HRhas huge input into company strategy as its cube (a form of balanced scorecard) was

    designed by a leading HR practitioner within the firm. The focus is on measuring talentacross the organisation, with particular concerns being raised about the role of solidperformers people who work consistently and effectively across the business.

    No strategic approach to measuring people within the organisation. Information generatedthrough an appraisal system is used for operational purposes only. Within a department storeenvironment in which there is low mobility between stores, it is claimed that managers havea good knowledge of the workforce and therefore more rigorous metrics are unnecessary.

    Company has been working on various aspects of human capital evaluation as part of thefirms commitment to total quality management. A major commercial crisis in the 1980s ledto a renewed and more strategic approach to HRM. The firm utilises different kinds ofcompetence-based systems for different groups of employees. Many of these consist ofperformance profiles that are linked to career progression.

    market performance in this area of the business, when will you get this

    product to the market. Not a single question on motivating people as a

    priority. So my judgement from that would suggest that market analysts

    are still some way off the concept of human capital being measured.

    Head of learning, TelecommsCoReflecting this indifference, our practitioner interviews revealed a strong preference

    for internal systems of reporting that is to say, information generated about members

    of staff is used for internal, management accounting purposes only. Internal reporting

    is non-standardised and enables the firm to develop a system of human capital

    evaluation that best serves its business needs.

    A summary of the main features of each cases approach to human capital

    evaluation is provided in Table 1. It is notable that there is considerable divergence in

    the different approaches. In part this reflects the flexibility of design granted by internal

    systems of reporting. But, as we shall see in the following section, these divergences inmanagement practice also reflect the factors influencing the adoption of human capital

    evaluation, as well as the real difficulties that firms face in dealing with such an

    intangible concept. Although some of the academic literature associated with

    accounting and human capital has been influential within certain case study firms we

    noted, for example, the widespread use of the balanced scorecard (Kaplan and

    Norton, 1996) managers also pointed out that there were limitations concerning the

    extent to which the ideas have been adopted wholesale by firms:

    there are a number of practices but none of them are terribly well

    developed in the way that Im familiar with in the human capital theories

    of people like Andrew Mayo. We are some way off developing that kind of

    approach to quantifying the value of the capability within our business as

    opposed to simply quantifying the number of people.

    Head of learning, TelecommsCo

    ACCOUNTING FOR DIFFERENCES IN HUMAN CAPITAL EVALUATION

    In the rest of this article we explore the factors explaining how and why these different

    approaches to human capital evaluation have emerged in practice. Such divergence in

    practice can be understood in a variety of ways. It can obviously be related to sectoraland contextual differences, given the range of firms involved (Child and Smith, 1987).

    It can also be seen as the result of UK managers tendency to pick and mix new ideas

    and techniques, rather than apply them in a uniform and consistent way (Storey,

    1989). Equally, this divergence in practice may be related to more structural factors to

    do with the distribution of power within the organisation and, particularly, the role

    the HR function plays within that distribution of power. Hoque and Noon (2001), for

    instance, identify a relationship between management practices and the labelling of

    the HR or personnel function within firms. Some of these questions are outside the

    scope of the present article. However, we did find some suggestive evidence ofsystematic variation in the forms of human capital evaluation employed by the firms

    in our sample. This variation is described in more detail below, while the subsequent

    section explores the linkages with the role and aspirations of the HR function in our

    sample firms.

    Differences in human capital evaluation in our study can usefully be analysed in

    terms of the two dimensions of practice described earlier. First, there are variations in

    the focus of a firms human capital evaluation practice. We observed in certain firms

    Juanita Elias and Harry Scarbrough

    27HUMAN RESOURCE MANAGEMENT JOURNAL, VOL 14 NO 4, 2004

  • 7/30/2019 Evaluating Human Capital

    8/20

    systems that were specifically focused on, for instance, the top 250 members of the

    management population (ie those whose managerial skills and competencies create

    most value) or on a specific talented population (eg insurance underwriters and ITspecialists). This talent focus seemed to contrast with firms that adopted a much wider

    focus on the value-creating skills and abilities of their workforce as a whole.

    The second major variation concerns the extent to which the firms sought to

    establish systems based on the collection of aggregate data as a counter-weight to

    financial indicators. This balancing act was often characteristic of firms that had

    adopted some form of the balanced scorecard (Kaplan and Norton, 1996), and

    respondents at these firms were keen to stress the strategically focused nature of the

    human capital evaluation system. For these firms, adoption of systems of human

    capital evaluation was linked to the attempted reformulation of the HR function as astrategic partner within the organisation. In contrast to these leading firms, for most

    firms in our sample the focus of human capital evaluation was on its individual aspects

    rather than on the development of aggregate measures designed to contribute to

    company strategic thinking and decision-making.

    Overall, then, our analysis of existing practice suggested that there were systematic

    variations in the forms of evaluation adopted according to the scope and objectives

    applied to the design of systems. By analysing the practice of human capital evaluation

    against these two dimensions we were thus able to identify, on a propositional basis,

    four possible styles of human capital evaluation.First, we identified firms that focused evaluation on an elite group that was

    perceived to have a strategic value to the business. Thus, at EngineeringCo and

    HitechCo, it was felt that systems of evaluating the worth of their senior management

    population would help to deliver senior managers capable of thinking strategically in a

    competitive global environment. As one manager commented:

    In the new era of companies that are knowledge based, if you dont

    manage your human capital and your competitors do, then they will beat

    you because they will get the best. Director of learning, HitechCo

    Thus, both of these firms cited the idea of the war for talent in justifying theadoption of human capital evaluation systems. These firms saw a strategic value in

    focusing their evaluation systems on the most talented and therefore most valuable

    senior managerial population. Developments here may thus reflect the link identified

    by Sisson and Scullion (1985: 36) between the scope of HR activities and the emergence

    of a core set of workforce skills as a strategic contingency. Certainly, the practice of

    human capital evaluation at EngineeringCo seems to reflect such a link. Here, we found

    that traditional HR practices such as collective bargaining were located at the level of

    the subsidiary, with few policies in place to ensure consistency in practice across the

    subsidiaries. At the same time, in a newly emerging strategic HR function, a smallteam of senior HR specialists had sought to concentrate human capital evaluation on a

    core senior managerial group. In contrast to these cases, we also need to note

    Armstrongs (1995) contrary argument that HRMs strategic presence may actually be

    downgraded when (as is more typical) firms diversify away from such core skills. This

    question of the link between human capital evaluation and the role of the HR function

    is a theme that is developed later.

    The second grouping that we identified was that which demonstrated a broad focus

    on evaluating its employee base and which displayed a recognition of the potentially

    strategic value of this process. This type of firm predominated in customer-drivenbusinesses such as those found in the retail sector or in service-sector firms operating

    large call centres. Managers in this latter group felt that long-term company value

    derived largely from improved customer service. Critically, this was seen as dependent

    on building loyalty and commitment across the workforce as a whole.

    These two groupings of firms (which, for the sake of convenience, will be labelled

    talent focused and customer focused) have adopted fairly sophisticated forms ofhuman capital evaluation. Although diverging in their focus, both sets were pursuing

    rigorous and metrics-driven approaches to evaluation. For example, in both groups we

    discovered that firms were attempting to draw on a range of more traditional HR

    metrics (eg appraisal data, customer feedback, data on employee training and

    development) and were attempting to utilise this data in order to produce more

    aggregate measures of employee performance. Managers in both groups of firms

    expressed the view that such measurement systems were a vital part of building and

    developing a strategic approach to HR (an issue that we develop later).

    In certain firms (EngineeringCo, HitechCo and ShopCo) this process was very

    advanced, and these firms sought constantly to re-appraise and monitor the kinds of

    metrics that they were using, feeding this data into strategic decision-making (often

    through some form of balanced scorecard mechanism) as well as into day-to-day

    operational HR decisions on training provision, promotions and remuneration. Other

    firms (RetailCo and InsuranceCo) were in the early stages of some kind of human

    capital evaluation system, although interviews revealed that they aimed to emulate

    those systems that were at work in leading companies such as EngineeringCo or

    ShopCo. For example, managers at RetailCo commented that they had been visiting

    other firms (including ShopCo) in order to learn about best practice in this area.

    A clear contrast to these leading firms was a third type that focused its evaluationof key individuals exclusively on financial performance outcomes, and which sought to

    retain this talented population through systems of high (and escalating) remuneration.

    Firms such as CityCo were clear examples of companies fighting a war for talent with

    a pure focus on systems of financial reward for top performers. We were keen to

    interview HR practitioners in City firms because such companies identify a core

    population of employees (investment brokers) as a key corporate asset, and we felt

    that, with their aggressive headhunting policies, they represented a clear-cut example

    of firms fighting the war for talent. Human capital was evaluated strictly in terms of

    the financial performance of the individual brokers. This is in contrast to most of the

    other firms in our sample, where human capital was seen as intangible, context-

    dependent and stemming from a complex web of difficult-to-measure soft skills. This

    applied even at firms such as InsuranceCo, where the professional skills of a group of

    insurance underwriters were evaluated against the same competency criteria applied

    to other employees.

    A final group identified were those where data on workforce competencies was

    gathered and utilised at the level of individuals only and was not aggregated to

    provide a more composite view of human capital at firm level. In these companies the

    evaluation of human capital did not extend beyond narrow functional concerns to do

    with the validity and effectiveness of employee appraisal systems.

    ROLE OF THE HR FUNCTION

    This section seeks to link the differences in practice observed in our study to the

    differing roles played by HR departments within our sample. Our interviews suggest

    that the nature of that link operated both at a general level and through more specific

    aspects of the way in which HR functions operated.

    The more general and pervasive aspects of the interplay between human capital and

    HR seemed to derive from two principal sources. First, there was evidence that the

    development of a more proactive approach to human capital derived from a significantchange in the firms market position. In several firms, this was seen as impelling a

    radical reorientation of the HR function with consequent implications for the treatment

    of human capital. Hence, at CopyCo managers discussed how the loss of its majortechnical patent in the 1980s led to a significant restructuring of management. This was

    seen as a process that paved the way for its current systems of human capital

    evaluation. Interviewees elsewhere also mentioned crisis points, such as a suddendownturn in profitability (RetailCo), calls for greater corporate social responsibility

    (OilCo) and a corporate merger that led to a new, strategic emphasis on human capital.

    A respondent at InsuranceCo described the latter process as follows:One of the benefits of the merger is that you actually do have a chance

    to start again in terms of policies, and you actually have to put new stuff

    in place. Director of HR projects, InsuranceCo

    A second, more general, influence on human capital evaluation came from theincreasing professionalisation of HR practices. Our findings here echo the work of Bellet al (2001) on Investors in People (IiP), who suggest that the IiP process acts as a

    mechanism for the codification and legitimisation of HR management practice, therebyenhancing the relative power of the function within the dynamics of the organisation.

    As they note:For the personnel function to be able to coalesce as an effective group of

    professional individuals that is distinct and recognisable to other

    managers, the personnel manager must engage in standardisation or

    codification of specialist knowledge. (Bell et al, 2001: 210)

    It could be suggested that such standardisation enhances professionalism byincreasing the ability of HR managers to define their professional identity through

    access to specialist knowledge (Friedson, 1994). We noticed similar processes at work inmany of our case study firms (particularly those that we identified as leading firms

    earlier). Although human capital is a term that many HR practitioners were reluctant to

    employ, more sophisticated metrics-driven approaches to measuring employeecompetencies were frequently seen as part and parcel of a reshaping of the HR function

    in line with a process of greater professionalisation. HR managers at OilCo, for

    example, talked about HR getting smarter in this context.The drive towards professionalisation, however, also highlights the implications of

    inter-professional competition in the development of human capital evaluation (Abbott,

    1988). In this context, Armstrongs (1995) work is highly relevant, warning of thedanger that confirmist innovations involving the standardisation and quantification of

    HR activities merely entrench the dominance of a management accountancyperspective. He claims that the provision of hard data for the accountingframework, and the evaluation of the outcomes of personnel activity in accounting

    terms (Armstrong, 1995: 158) simply encourages the contracting out of personnel work

    and undermines the case for a distinctive personnel approach.It is not possible within the scope of this study fully to evaluate this argument,

    which is broad based and historical in nature. We can observe, however, that in all our

    case studies the process of human capital evaluation was an HR-led initiative. Inparticular, our interviews revealed that the views of HR managers were closer to the

    normative literature in this field which sees human capital evaluation as actuallyenhancing the strategic role of the HR function within the firm (Becker et al, 2001;

    Evaluating human capital: an exploratory study of management practice

    30 HUMAN RESOURCE MANAGEMENT JOURNAL, VOL 14 NO 4, 2004

  • 7/30/2019 Evaluating Human Capital

    11/20

    Berkowitz, 2001; Bontis and Dragonetti, 1999; Fitz-Enz, 2000; Hitt et al, 2001; Lee and

    Miller, 1999; Mayo, 2001). This leads to the tentative conclusion that, at this stage in its

    development at least, human capital evaluation is not subordinate to accountancy

    criteria, but potentially provides a space within which HR tools and practices (eg

    training and development) may be legitimised in terms of their ability to build long-term value for the firm. In this sense, human capital evaluation may represent a

    deviant form of innovation (Legge, 1978), challenging rather than reinforcing the

    management accountancy perspective.

    The prospect that HR functions may actually be able to enhance their role within the

    organisation although the appropriation of these measurement tools and techniques

    reinforces, rather than detracts from, a concern with questions of power and control as

    key to understanding the practice of human capital evaluation. With this in mind, the

    following (albeit somewhat indicative) observations can be made.

    First, we found a possible relationship between the level of sophistication of systems

    of human capital evaluation and the strategic role of the HR function. In certain cases,

    by stimulating greater managerial attention towards issues of human capital, the new

    flows of information created by measures of employee performance and competency

    seemed to have at least the potential to support the strategic aspirations of the HR

    function. This relationship with the role of HRM was not one way, however. Our

    second observation was that the evaluation of human capital was seen in some of our

    firms as enhancing the credibility of the HR function with other groups. At ShopCo, for

    example, the interviewee suggested that the process of human capital evaluation had

    enabled the HR function to be taken more seriously by the rest of the business. The

    point was made that HRMs human capital goals (which at this firm were viewed interms of the necessity to deliver a loyal and committed workforce in order to create

    corporate value) needed to be recognised as essential components of successfully

    achieving company strategic goals:

    Its a company goal to have the most loyal and committed staff, and the

    reason we believe that is that you cant actually deliver engaging customer

    service unless youve got committed people. You can see that straight

    away its the old stories of going into a record shop and seeing people

    totally ignoring you. But if you have got somebody who is really

    motivated to deliver and committed to the business, then you are going tofeel more likely that they are going to care about you as a shopper and

    youll probably come back. So its a very sensible reason, really, and the

    business believes that. Its not HR smoking dope stuff!

    HR measurement unit director, ShopCo

    Greater credibility was also seen as linked to the adoption of more objective metrics.

    Such metrics did not necessarily require new tools. For example, some firms had

    identified the appraisal system as the best way to generate aggregate measures of

    employee competencies across the organisation. At EngineeringCo and HitechCo,

    however, a larger range of metrics was employed (including human capital datagenerated from appraisals, peer review, employee feedback and customer feedback),

    leading to perhaps more accurate assessments of employee competencies.

    One implication of the adoption of human capital metrics was the greater ability to

    relate HR concerns to wider business issues. This echoes Johansons study of human

    capital evaluation in Sweden, whereby a process of Human Resource Cost Accounting

    (HRCA) had enabled managers to identify connections between human resources and

    financial results (Johanson, 1999: 95). As an interviewee at ShopCo observed, the key

    Juanita Elias and Harry Scarbrough

    31HUMAN RESOURCE MANAGEMENT JOURNAL, VOL 14 NO 4, 2004

  • 7/30/2019 Evaluating Human Capital

    12/20

    issue in terms of human capital evaluation was:

    taking the business with you so that they understand it and why you are

    doing it and not overloading the business. The first step in getting thebusiness to understand you is to have data and information that is arguing

    why you need to do it and what the impact is going to be.

    HR measurement unit director, ShopCo

    This is not to say that the adoption of metrics necessarily precluded attention to less

    tangible aspects of the role of HR, as has been suggested in some studies (Grugulis and

    Bevitt, 2002). A concern with measurement may certainly create a tension between the

    quest for rigorous (scientific) objective measurement systems and the traditional roles

    and functions of HR in industrial relations and everyday people management practices

    (Armstrong, 1995). However, it must also be recognised that the HR-led nature of this

    process in our case studies seems to have avoided the simplistic equation of employee

    competencies with financial inputs and outputs. Rather, in a number of cases,

    managers have developed more complex understandings of what drives company

    performance. Indeed, in several cases the process of human capital evaluation was

    explicitly linked to the development of company values, which were to be cascaded

    throughout the organisation. At EngineeringCo, for example, the company had

    developed a list of key competencies and behaviour for business leaders that were

    viewed as driving business success. Individual performance was measured against

    these specifications. Thus, at EngineeringCo, in sharp contrast to CityCo, for instance,there was a strong concern not to neglect softer skills in the way in which managers

    set about achieving their targets:

    We started by saying its [performance] about achieving business targets

    and its about achieving individual objectives, but it is also about the way

    in which you do it. So if you just achieve all your business targets and

    achieve all your personal objectives but you do it in an inappropriate way

    you destroy people in the way that you do it then you fail the

    performance criteria. So these five competencies and 40 behaviours are all

    about driving for an improved performance in an appropriate manner

    one that is people-centric. HR director, EngineeringCo

    A fourth mechanism linking human capital to the role of HR could be identified in

    evidence of the organisational change and differentiation within that function. This was

    specified most explicitly at ShopCo:

    The business came to the conclusion that we [HR] had to really shake

    things up if we wanted to become a strong global retailer which is one of

    our goals and we went through a complete relaunch of the HR function

    close to three years ago... that led us to really being far clearer as to whatthe people processes are that we are delivering.

    HR measurement unit director, ShopCo

    This reorientation of the HR function was linked in some cases to the development

    of new specialised units dedicated to developing workforce capabilities for strategic

    goals (RetailCo, ShopCo, HitechCo). These units were often closely focused on

    measurement. Perhaps the best example of this was at ShopCo. Here, they had

    developed a People Innovation Unit whose raison dtre was to improve how human

    capital was measured in a way that maximised value for the business. At RetailCo,

    we saw the development of an Employee Insight Unit (EIU) which was focused onmaking the organisation a great place to work through the development of

    Evaluating human capital: an exploratory study of management practice

    32 HUMAN RESOURCE MANAGEMENT JOURNAL, VOL 14 NO 4, 2004

  • 7/30/2019 Evaluating Human Capital

    13/20

    employees emotional loyalty. This units work revolved around means of

    quantifying and operationalising such terms through, for example, the targeteddesign and distribution of employee feedback questionnaires. The work of the EIU

    thus exemplified certain aspects of a human capital approach, inasmuch as it was

    based on measuring what would previously have been regarded as unmeasurable,

    intangible and soft.

    The development of these innovative units could also be seen as a response to the

    credibility concerns voiced by many HR managers about developments in this area. A

    senior manager at EngineeringCo, for example, commented on his worry that their

    systems for human capital evaluation would not be taken seriously across the whole

    business:I was absolutely determined that this was not going to be an HR

    initiative At the launch of the programme.. the chief exec presented it

    all, supported by the three chief operating officers who took everyone

    through the details I didnt stand up and do anything. This was

    absolutely important because if you are not careful it becomes an HR

    initiative, not a business strategy. Director of HR, EngineeringCo

    Such concerns among HR practitioners were also apparent in Bell et als study of IiP,

    in which the personnel and training managers were keen to undermine the perception

    that the process was essentially a personnel thing (Bell et al, 2001: 209).A summary of the findings from this study relating to the interplay between human

    capital evaluation and the changing role of HR are presented in Table 2.

    IMPLICATIONS FOR PRACTITIONERS

    Table 2 highlights the impact of human capital evaluation on the HR professionals in

    many of the firms that we studied. It is useful, therefore, to turn to some of the wider

    implications for practitioners to ask what human capital evaluation means for the

    HR profession.While recognising that this was an exploratory study confined to a sample of 11

    large UK firms, a number of themes emerge that have direct relevance to theevolution of HR practice in the UK. First, our research suggests that there is no holy

    grail no universal formula to measure the value of employee skills and

    competencies. Human capital is tacit and dynamic and therefore needs to beevaluated with the (constantly changing) needs of the firm and other stakeholders in

    mind. From our study, the nature of human capitals contribution to the business

    varies significantly between firms.

    Although our research does not allow us to elaborate on the contextual sources ofsuch variation, it does suggest some future avenues for research. In particular, one

    initial observation derives from the broad distinction between a broad and narrow

    focus on human capital evaluation. These differing managerial responses seem to belinked to different dynamics in the formation of human capital. Thus, the broad focus

    was developed in relation to widely dispersed customer service skills. Such front-line

    skills involve a significant element of emotional labour (Korczynski, 2002), and thiswas reflected in the more affective emphasis of evaluation in such settings. Conversely,

    we found that the narrow focus had developed in response to specific concentrations of

    expertise which were more closely evaluated in relation to technical-managerial

    competencies. Such findings suggest that, above and beyond industrial sectordifferences, the interplay between the organisational context and the distribution and

    formation of human capital may be an important component in the variations found inour sample.

    A further key implication for practitioners, reflecting the context-dependent nature

    of human capital, is the need to review continuously the indicators that they use inthe light of a changing business environment. This suggests that human capital

    evaluation is best viewed as a learning process through which managers come to

    appreciate the often tacit or misunderstood contribution that employee skills and

    competencies make to the achievement of business objectives. This, certainly, is amore robust approach than one that emphasises the generation of statistics, which are

    in themselves inevitably provisional and context-dependent. Such considerations

    lead us to the conclusion that the process of human capital evaluation is at least asimportant as its immediate outcomes.

    In terms of management practice, we also need to address Armstrongs concern

    about the shift towards a management accountancy perspective and its implications forthe HR function. Here, our study suggests that metrics-driven approaches are double-

    edged in their effects, having the potential to act as both deviant and conformist

    innovations. Although developments in our sample companies are still at an earlystage, we found that in certain firms, notably those with HR-led measurement units,

    Evaluating human capital: an exploratory study of management practice

    34 HUMAN RESOURCE MANAGEMENT JOURNAL, VOL 14 NO 4, 2004

  • 7/30/2019 Evaluating Human Capital

    15/20

    HR practitioners are setting an agenda for measurement that avoids the reductive

    assumptions of the management accountancy approach. We note, for example, the

    emphasis of measurement systems at ShopCo on the determinants of employee loyalty

    and commitment. It is too early to say whether such initiatives represent a significant

    deviation to the institutional weight of accounting practice (Armstrong, 1995: 151),but in this case and in others in our sample metrics helped to legitimise activities

    that are integral to the HR function.

    CONCLUSIONS

    The contribution of this article was defined at the outset in terms of the need for

    evidence on the practice rather than on the theory of human capital evaluation. We

    noted that existing normative approaches tended to gloss over the practical aspects of

    evaluating human capital, and of linking that evaluation to action. In contrast, our

    study was concerned to explore the development of management practice, and ourresearch questions were consequently focused on what were seen as important

    dimensions of such practice: scope, level of application and overall style. In this

    respect, our study sought to illuminate both the varieties of current practice and the

    reasons for such variety. Without rehearsing our major findings once more, it is worth

    noting that the uniform preference among our case firms for the internal reporting of

    human capital seems to have reflected not only the lack of interest among important

    external audiences, but also the absence of any universal formula that could be applied

    across different industrial contexts. Our experience in the field was that firms, while

    drawing on ideas such as the inclusion of people metrics in the balanced scorecard,actually adapted these approaches to their own company needs, preferring flexibility to

    standardised systems of reporting. Moreover, systems for evaluation were not only

    organisation-specific in terms of the definitions of competence employed reflecting,

    we would argue, the context-dependent nature of human capital itself but also in

    terms of the factors that shaped their design and use. These latter factors draw

    attention to the influence of the organisational context on management practice in this

    area, and the greater part of the article was thus devoted to exploring and unpacking

    that influence.

    We did this, first, through an account of the different styles of human capital

    evaluation evident in our study. In relating these different styles to context, it is

    possible to identify, first, a broad influence on practice relating to sector and/or forms

    of human capital. Thus, the high-tech firms in our sample were concerned with

    specialised skills and focused on the value of highly talented individuals. The retailers,

    on the other hand, developed measures that were applicable to the whole of their

    workforce and which were focused on the creation of customer value and loyalty.

    Beyond these influences, however, our study also suggested an organisational effect,

    whereby practice on human capital was linked to the role of the HR function within the

    firm. Variations here seemed to be related to the different goals that HR professionals

    were pursuing with evaluation, ranging from what were seen as strategic goals to morenarrow operational concerns. Thus, our study suggested a reciprocal relationship

    between the forms of human capital evaluation adopted and the development and

    differentiation of the HR function itself.

    This latter finding highlights the generative possibilities of new practices based on

    the concept of human capital. It thus brings us to our final conjecture on the role that

    human capital may help to play in mediating HR-business interactions. As an

    exploratory study, our research has tended to reveal not only the specific usages of

    Juanita Elias and Harry Scarbrough

    35HUMAN RESOURCE MANAGEMENT JOURNAL, VOL 14 NO 4, 2004

  • 7/30/2019 Evaluating Human Capital

    16/20

    human capital in particular settings but has also helped to reveal more immanent

    tendencies in its development. In particular, a recurrent theme in our study, as reflected

    in the findings above, is the role that human capital plays as what can be termed alinking concept in ongoing organisational debates and struggles on the contribution ofemployees to corporate performance. Human capital can be seen as providing such a

    linkage in several different areas of existing practice. First, the development of metrics

    centred on human capital provides a link between the HR function and other

    managerial groups, not least senior management, whose practices are typically drivenby quantifiable objectives and metrics. The ability to translate what are sometimes seen

    as nebulous aspects of employee motivation and behaviour into measurable (hence,

    arguably manageable) phenomena may be a significant development in gaining greater

    credibility for the HR role. Secondly, for HR practitioners themselves, the ability torelate their activities to an identifiable and measurable set of outcomes, which are

    employee and not financially based, may provide a way of linking so-called hard and

    soft variants of HRM (Storey, 1989). Finally, taking these points together is to identifysome of the means through which HR functions may be able to develop a link between

    the effects of their day-to-day practice and the strategic aspirations of the firm and

    without bracketing such aspirations in narrowly financial terms.
