Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University4

What is Strategy

Definition of strategy

� Early 1990s definition:

� “A well coordinated set of objectives, policies, and plans aimed at securing a long-term competitive advantage. A vision for the organization that is implemented.”

� Webster’s Dictionary

� “a careful plan or method”

� “the art of devising or employing plans toward a goal”

� “the art and science of military command exercised to meet the enemy in combat under advantageous circumstances”

What is Strategy?

� Strategy

� Henry Mintzberg:

� Explicitly planned: “Intended Strategy”

� Realized: planned and succeed

� Unrealized: planned but fail

� Implicit, not explicitly planned yet executed: “Emergent Strategy”

Strategic Advantage and ITEvolution of Strategy Concepts

� Three eras of approaches for achieving strategic advantage

� Portfolio of Business (1970s)

� performance a result of businesses you pick to be in

� motivated by economies of scale

� Portfolio of Capabilities (mid 1980s)

� performance a result of internal processes and routines, which provide distinctive capabilities

� motivated by economies of scale and scope

� Portfolio of Relationships (mid 1990s)

� performance a result of building a wide array of relationships with external companies that possess hard-to-imitate capabilities

� motivated by economies of scale, scope, and expertise

IS as a Strategic Resource

� Hayes and Wheelwright (1985) - operations effectiveness, applies equally well to ISD effectiveness

� Stage 1: Internally Neutral

�not seen as a source of process improvement technology

�Minimize negative impact of functional area on organization

�Top management “in control”; tells dept. what to do

� Stage 2: Externally Neutral

�not seen as a source of external competitive advantage

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University10

IS as a Strategic Resource (cont…)

� Stage 3: Internally Supportive

�source of internally focused competitive advantages

� Stage 4: Externally Supportive

�viewed as competitive force in the business

�function drives issues of top-management strategy making

Porter’s five forces model

� Professor Michael Porter of Harvard University maintained that in every industry, competition depends on the collective strength of five basic forces

� Interacting with these forces are the generic corporate strategies.

� IT can be a powerful agent to change the balance of power in and between these forces.

Page 7: Introduction to Technical Writing  (Technical Writing CS212)

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University13

Porter’s five forces model (cont…)

� Michael Porter has identified five forces that are widely used to assess the structure of any industry. Porter’s five forces are the:

� Bargaining power of suppliers,

� Bargaining power of buyers,

� Threat of new entrants,

� Threat of substitutes, and

� Rivalry among competitors.

Porter’s five forces model (cont…)

� All organisations operate in one or more industries.

� By the nature of their participation in an industry, they are affected by existing or potential uses of information technology

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University16

Porter’s five forces model (cont…)� New entrants can increase overall capacity in the

industry, thereby reducing prices and incumbents' cost advantages.

� Market is cornered with product, but success may inspire others to enter the business and challenge position. The threat of new entrants is the possibility that new firms will enter the industry.

� New entrants bring a desire to gain market share and often have significant resources. Their presence may force prices down and put pressure on profits.

� IT can help create or raise barriers to entry by increasing mandatory investments in hardware and software, facilitating control over databases, or locking in customers to existing distribution channels.

� There are many types of barriers to entry: � switching costs, economies of scale, high investment in IT, economies of experience, access to distribution channels, and government policy

Porter’s five forces model (cont…)

� Intensity of industry rivalry depends on factors beyond the control of the individual firm,

� such as degree of concentration, diversity, or dependency; rate of industry growth; or switching costs.

� It is critical to understand the strategies of one's rivals in detail.

� For instance, Ford's strategy depends on the strategies of Toyota, Nissan, GM, and Volkswagen, and vice versa.

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University18

Porter’s five forces model (cont…)

� Threat of substitute products may arise from products and services in other industries.

� Examples:

� * the products of stock brokers and insurance companies now compete against banks for the investment dollar.

� * the automobile eliminated the horse with buggy, and the silicon chip eliminated electromechanical adding machines. The life cycle of products can be reduced through the use of IT, such as Computer-Aided Design (CAD). IT has also provided the basis for creating new information-intensive products.

Porter’s five forces model (cont…)Bargaining power of buyers � The power of buyers describes the effect that your

customers have on the profitability of your business. The transaction between the seller and the buyer creates value for both parties.

� Buyers drives prices down and the quality of products up.

� Buyer power depends on the level of switching costs, the competitive position of the buyer in the industry (size, volume), whether the buyer can purchase a commodity product, or whether the buyer poses a serious threat of backward integration (i.e., buying out or merging with its suppliers).

� Installing computer terminals at the buyers' site is one way to raise the buyers' cost of switching to other suppliers.

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University20

Porter’s five forces model (cont…)

Bargaining power of suppliers

� Any business requires inputs—labor, parts, raw materials, and services. The cost of your inputs can have a significant effect on your company’s profitability. Whether

� It is in some ways the antithesis of buyer power.

� The threat of forward integration (i.e., buying out or merging with its customers) is one determinant of supplier power.

� Influential suppliers drive prices up and reduce the quality and quantity of products and services.

� Supplier power also depends on size, volume, and concentration relative to other firms in the industry.

Porter’s five forces model (cont…)

� Together, the strength of the five forces determines the profit potential in an industry by influencing the prices, costs, and required investments of businesses—the elements of return on investment.

� Stronger forces are associated with a more challenging business environment.

� To identify the important structural features of your industry via the five forces, you conduct an industry analysis that answers the question, � “What are the key factors for competitive success?”

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University22

Value Chain Analysis

� The value chain is a systematic approach to examining the development of competitive advantage.

� The chain consists of a series of activities that create and build value. They culminate in the total value delivered by an organisation.

� The 'margin' depicted in the diagram is the same as added value. The organisation is split into 'primary activities' and 'support activities

Value Chain Analysis (cont…)

� The value chain begins with the data resource.

� Information is developed from the data resource to support the knowledge environment of an intelligent learning organisation.

� Data is the raw material for information which is the raw material for the knowledge environment.

� Knowledge is the raw material for business intelligence that supports business strategies.

Electronic Data Interchange (EDI)� EDI was first developed by the automobile/transportation industry in the 1970s.

� Today, � it is widely used in a variety of industries, including distribution, finance and accounting, health care, manufacturing, purchasing, retail, tax form filing, and shipping.

� Early,� EDI packages used rather simple standard forms that forced companies to convert data to fit the forms.

� Newer, � EDI systems allow companies to create custom systems using simple programming or authoring tools.

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University26

Electronic Data Interchange (EDI) (cont…)

� Electronic Data Interchange (EDI) is the electronic exchange of routine business transactions.

� EDI defines the electronic exchange of structured business data, such as purchase orders, invoices, and shipping notices, typically between one organisation and another.

� Typical transactions include such documents as purchase orders, invoices, advance shipping notification, payments, etc.

� Exchange of electronic data using inter-organisational information systems

� Set of hardware, software, and standards that accommodate the EDI process

� The relationship is usually between a vendor and customer.

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University27

Electronic Data Interchange (EDI) (cont…)

� It is important to differentiate between EDI and electronic commerce (e-commerce).

� Electronic commerce encompasses all aspects of electronic business exchanges, including person-to-person interaction (collaboration), money transfers, data sharing and exchange, Web site merchant systems, and so on.

� EDI as a subset of electronic commerce that encompasses the exchange of business information in a standardised electronic form.

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University28

Electronic Data Interchange (EDI) (cont…)

� EDI can reduce costs, workforce requirements, and errors associated with retyping orders, invoices, and other documents.

� With EDI, computer data already entered by one organisation is made available to a business partner.

� EDI is typically handled using store-and-forward technologies similar to e-mail.

Page 15: Introduction to Technical Writing  (Technical Writing CS212)

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University29

Electronic Data Interchange (EDI) (cont…)

� Two approaches in the implementation of EDI.

�Many large organisations acquire or build their own proprietary systems, often in association with their business partners.

�To work with a value added network provider, which provides EDI transaction services, security, document interchange assistance, standard message formats, communication protocols, and communication parameters for EDI.

Value Added Network (VAN)

� A (VAN) Value Added Network is a third party who stores the data to be communicated.

� Serves as a middle person, so neither party can access the other’s private network.

� The main key to a VAN is that the other partner does not touch your network, as business partners initiate the sending or retrieving of the data from the VAN.

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University32

Value Added Network (VAN) (cont…)

� With the data being sent to or received from the VAN by the business partners initiating the communication, business partners are insuring a safe method of data transportation.

� The different ways of communicating to the VAN include dialup as well as FTP protocols.

Business intelligent agents

� Business intelligence represent a popular trend in many public and private sector organisations.

� Ideally, any manager or knowledge worker should be able to compose information requests without programmer assistance and achieve answers at the speed of thought.

� Follow-up questions should be immediately asked and answered in order to maintain continuity of thought on a particular topic of importance.

Page 18: Introduction to Technical Writing  (Technical Writing CS212)

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University35

Business intelligent agents (cont…)

� Intelligent Agents execute tasks on behalf of a business process, computer application, or an individual.

� For example, corporate use of monitoring software based on agents can be a key component in cutting support costs and increase computer efficiency.

� Intelligent agents have been written to search through e-mail messages for certain keywords or simple concepts (phrases).

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University36

Business intelligent agents (cont..)

� Knowledge-based expert systems, or simply expert systems, use human knowledge to solve problems that normally would require human intelligence.

� These expert systems represent the expertise knowledge as data or rules within the computer.

Data warehouse, data marts

� Data warehouses are computer based information systems that are home for "secondhand" data that originated from either another application or from an external system or source.

� Warehouses optimize database query and reporting tools because of their ability to analyse data, often from disparate databases and in interesting ways.

� They are a way for managers and decision makers to extract information quickly and easily in order to answer questions about their business.

� In other words, data warehouses are read-only, integrated databases designed to answer comparative and "what if" questions.

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University38

Data warehouse, data marts (cont…)

� Data Marts:� Data in a data warehouse should be reasonably current, but not necessarily up to the minute, although developments in the data warehouse industry have made frequent and incremental data dumps more feasible.

� Data marts are smaller than data warehouses and generally contain information from a single department of a business or organisation. The current trend in data warehousing is to develop a data warehouse with several smaller related data marts for specific kinds of queries and reports.

Data mining

� Data mining is primarily used today by companies with a strong consumer focus -retail, financial, communication, and marketing organisations.

� It enables these companies to determine relationships among "internal" factors such as price, product positioning, or staff skills, and "external" factors such as economic indicators, competition, and customer demographics.

Page 21: Introduction to Technical Writing  (Technical Writing CS212)

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University41

Data mining

� Data mining, or knowledge discovery, is the computer-assisted process of digging through and analysing enormous sets of data and then extracting the meaning of the data.

� Data mining tools predict behaviors and future trends, allowing businesses to make proactive, knowledge-driven decisions.

� Data mining tools can answer business questions that traditionally were too time consuming to resolve.

� They scour databases for hidden patterns, finding predictive information that experts may miss because it lies outside their expectations.

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University42

Data mining (cont…)

� With data mining, a retailer could use point-of-sale records of customer purchases to send targeted promotions based on an individual's purchase history.

� By mining demographic data from comment or warranty cards, the retailer could develop products and promotions to appeal to specific customer segments

Page 22: Introduction to Technical Writing  (Technical Writing CS212)

Abdisalam Issa-Salwe, College of Computer Science & Engineering, Taibah University43

Data mining (cont…)

� Data mining consists of five major elements:

� Extract, transform, and load transaction data onto the data warehouse system.

� Store and manage the data in a multidimensional database system.

� Provide data access to business analysts and information technology professionals.

� Analyse the data by application software.

� Present the data in a useful format, such as a graph or table.
