processes and• Professional quality practices within the organization’s normal business operations

Striving for the business-integrated quality management

Answers to these questions may be differentin different practical organizational cases.Hence, also the solutions of the embeddedquality management may also differ greatlyamong different organizations.

Fundamental understanding of the topic:- Without a proper answer to the followingquestions, the business-integrated qualitymanagement is not possible:

How to understand organization?How to understand management?How to understand quality?How to understand quality management?

One cannot distinguish the business-integrated quality management from the businessmanagement of an organization.• The approach is a deliberate countermeasure to separate quality systems.The business-integrated quality management is to reinforce an organizational business identity.• The approach is to stand out amongst the crowd of look-likes of standard image with regard

to quality in striving for business competitiveness.

Joseph Juran, Quality control handbook (1974):“Any widespread discipline must identify and clarify the universal concepts, which underlie itsvery existence as a discipline. In addition, it must evolve and standardize the key words andphrases through witch the practitioners of the discipline can communicate with each other. The quality function has taken some steps to identify and clarify these concepts to preparesome glossaries of terms. Because they have not been widely adopted (or even circulated), thereis great difficulty in reaching a meeting of the minds when practitioners convene to solveproblems.--- The reader is urged to keep in mind that differences in meanings of key words and phrases area frequent source of confusion. The question “Just what do you mean by this word” is especiallyimportant in those cases where someone else is drawing an “illogical” conclusion from theidentical set of facts. Such outward differences in conclusions are seldom the result of illogicalreasoning. More usually they are the result of logical reasoning from different concepts orpremises.”

What is business management all about?

4152/11.1.2014/jan

Creators of the classicalschools of management theory:

F.W Taylor 1856 –1915Scientific management (productionoperations)

1. Replace rule-of-thumb workmethods with methods basedon a scientific study of thetasks

2. Scientifically select, train, anddevelop each employee ratherthan passively leaving them totrain themselves

3. Provide detailed instructionand supervision of each workerin the performance of thatworker's discrete task

4. Divide work between managersand workers; the managersapply scientific managementprinciples to plan the work andthe workers perform the tasks.

H. Fayol 1841 –1925Industrial administration (strategic management)1. Division of work among individuals and groups to focus effort and

attention on special portions of the task2. Authority of managers to give orders.3. Discipline. Employees obey and respect the rules4. Unity of command. Every employee gets orders from only one

superior5. Unity of direction. Each group with the same objective is directed

by one manager using one plan6. Subordinate individual interests to the general interest of the

organization as a whole7. Remuneration. Workers must be paid a fair wage for their

services.8. Centralization to find the optimum degree of centralization for

each situation9. Scalar chain. The line of authority from top management to the

lowest ranks represents the scalar chain. Communications followthis chain

10. Order. People and materials should be in the right place at theright time.

11. Equity. Managers should be kind and fair to their subordinates12. Stability of tenure of personnel. High employee turnover is

inefficient. Management should provide orderly personnelplanning

13. Initiative. Employees who are allowed to originate and carry outplans will exert high levels of effort

14. Esprit de corps. Promoting team spirit will build harmony andunity within the organization

The business-integrated quality management:• Is applicable in all and any kind of organizations• Is a natural and professional way to improve an organization’s business competitiveness

with regard to quality• Is based on organizations’ existing practices of management and quality, which factually

means that every organization always has a certain level of quality management• May always be improved according an organization’s business needs and business

decisions. A foundation for recognizing and developing an organization’s business-integrated quality management is to identify the organization’s business system andmanaging processes (The “organizational profile”)

• Is always ready but may never get finished• Is flexible to make creatively use of all concepts, principles and methodologies of the whole

recognized quality discipline• Is able to cover, in addition to quality management, also all other managerial disciplines,

e.g. according to the corresponding management system standards

4258/15.1.2014/jan

The challenge of the integration

The business-integrated approach is in principle and in practicedifferent from the integrated management systems where severalseparated management systems based on different managementsystem standards are realized as one single management system.

All organizations have• Different business needs• Different interested parties• Different business management approaches• Different emphases, selections, and applications in quality policies, principles,

practices, and methodologies

Hence, the business-integration is an organization-specific solution.

Particularly startups and small organizations need a special reflection but in thesecases quality, quality management and business integration are more important.

The business-integration is alwaysan organization-specific solution

Effective dialogue and cooperation is neededbetween business leaders and experts

Business leaders know the right things and experts know the best means todo things right:

• Business leaders are generalists and strongly acting individuals withstrong organizational positions. Normally they don’t have a deepknowledge of quality management.

• Experts are specialists and deeply knowing individuals with low position-based authority.

Clear responsibility / authority roles should be established between businessleaders and experts, and an effective dialogue and cooperation betweenthem made possible.

Promoting business-integrated quality managementas a regional approach

4262/11.2.2013/jan

Geographical regions, e.g. a country, are networked communities of various organizationaland individual actors. Organizations, which may be private business companies, public civilservice organizations, and the third sector voluntary organizations, are independent but inmany complicated ways interlinked with each other. Business-integrated quality managementapproach is applicable in all types of organizations, but each organization makes its owndecisions and selections by itself.

Business-integrated quality management may be promoted region-widely by:• Shared experiences of the pioneer companies• Organizations educating, training, coaching, and supporting professional quality and

quality management practices• Collaboration among organizations• Related research activities

In all cases the approaches of business-integrated quality management should berealized in accordance of the business situations and needs of the particularorganizations.

The Quality Integration approach:

- The integration covers all the subject areas considered within the ISO 9000standards and performance excellence models (quality awards criteria).- Also the topics of many other specialized management areas, e.g. environmentalmanagement, safety management, risk management, and information securitymanagement, etc., are typical sub-domains of Quality Integration.- One can also find significant ideas of Quality Integration from teachings ofrecognized gurus of quality profession and through benchmarking from the practicesof world class organizations.- Quality management equals quality of management.

We call this Quality Integration. It was invented as a concept and introduced to practicalbusiness solutions at Sonera Corporation in the 1990's.
