Organization has a limited set of resources (e.g. time, people, money, physical resources) and they must decide how to use those resources. Example: You have the following resources: $500,000 A building 10 employees A patent on new invention Strategy is deciding what the organization is going to do and how it will use use its resources Examples of Strategies : Examples of Strategies Strategy 1: manufacture equipment with the money and use the building and the people to manufacture widgets. Strategy 2: Outsource the production of widgets and use the people and building to be widget distributor - or perhaps a widget store. Strategy 3: Sell the patent to a larger firm, sell the building, fire the employees and retire! Strategy vs. Tactic : Strategy vs. Tactic Strategy focuses essentially on deciding on what the organization is trying to do, what it is trying to become within its business environment. Changing strategy is difficult and often causes problems. Tactic is the implementation of the strategy. It is the set of management decisions focussed on how to achieve the strategic objectives. Example: once the organization decides that it wants to be a widget manufacturer, there are many decisions that must be made about how to profitably manufacture widgets. Strategic Decisions : Strategic Decisions Strategic decisions address questions such as: What products or services will be provide? Will we focus on providing low cost goods/services? Will we focus on providing unique goods/services? Where will we sell our goods/services? To whom? IT can assist the strategic decision maker (e.g. ESS). More importantly, IT is likely to be critical to the implementation of the strategy. Elements of Strategic Management : Elements of Strategic Management Long range planning Responsive management Innovation The Role of IT : The Role of IT Create systems that provide strategic advantage Supports strategic changes, such as business reengineering Provides business intelligence Competitive intelligence Sustainable competitive advantage Competitive Advantage : Competitive Advantage What makes strategy difficult is that most business environments are competitive. Need to try to "second guess" the competition. Competitive advantage: what sets the firm apart from the rest of its competitors. Basis for competition: cost, speed, quality, variety, level of service,... Strategic Information Systems : Strategic Information Systems Strategic information systems computer systems at any level of an organization that change the goals, processes, products, services, or environmental relationships to help the organization gain a competitive advantage Information considered as a resource, much like capital and labor IT-critical competitive strategies: Customer lock-in, customer lock-out, new business entry Slide 30: STRATEGY LEVELS AND INFORMATION TECHNOLOGY (IT) - ANOTHER FRAMEWORK STRATEGIES MODELS IT TECHNIQUES INDUSTRY cooperation vs. competition Competitive forces electronic transactions licensing Network economics communications networks standards Inter-organizational systems information partnership FIRM Synergy Core competency knowledge systems Core competencies organizational systems BUSINESS Low Cost producer Value chain analysis data mining Differentiation of products/services IT-based products / services Scope of competition (global vs. niche) Inter-organizational systems supply chain management efficient customer response Slide 31: Value Chain Analysis Highlights the primary and support activities that add a margin of value to a firm’s product/service where IS can best be applied to achieve a competitive advantage. Primary activities: Activities most directly related to the production and distribution of a firm’s products/services Consist of inbound logistics, operations, outbound logistics, sales and marketing, service Support activities: Activities that make the delivery of primary activities possible Consist of organization’s infrastructure, human resources, technology, procurement The Value Chain for a Restaurant : The Value Chain for a Restaurant Each box represents a primary process IS to Support Product/Service Differentiation : IS to Support Product/Service Differentiation Product/service differentiation strategy for creating brand loyalty by developing new and unique products/services that are not easily duplicated by competitors e.g. Citibank’s ATM IS to Support Niche Focus : IS to Support Niche Focus Focused differentiation strategy for developing new market niches for specialized products/services Data mining analysis of large pool of data to find patterns and rules that can be used to guide decision-making and predict future behavior e.g. direct marketing Applications of Data mining Identifying individuals or organizations most likely to respond to a direct mailing. Predicting which customers are likely to switch to competitors. Identifying common characteristics of customers who purchase the same product. IS to Support Low Cost Strategy : IS to Support Low Cost Strategy Supply chain management integrates supplier, distributors, and customer logistics requirements into one cohesive process to reduce inventory cost or underutilized staff e.g. Wall-Mart’s “continuous replenishment system” “lock in” customer and raise “switching costs” expense a customer incurs in lost time and expenditure of resources when changing from one supplier to a competing supplier e.g. Baxter Healthcare’s “stockless inventory” Business Level Strategy : Business Level Strategy Firm-Level Strategies : Firm-Level Strategies A firm is a collection of business units Synergy outputs of some business units used as inputs to other units IS to tie operations of business units Core competencies activities at which a firm is a world-class leader IS to encourage sharing of knowledge Industry-Level Strategies : Industry-Level Strategies Competition with other firms Cooperation through information partnership e.g. American Airlines and Citibank Models to help analysis Competitive forces Network economics based on concept of a network where adding another participant entails no marginal costs but can create much larger marginal gain Slide 39: COMPETITIVE FORCES MODEL THE FIRM TRADITIONAL COMPETITION NEW MARKET ENTRANTS Bargaining power of SUPPLIERS Bargaining power of CUSTOMERS SUBSTITUTE PRODUCTS & SERVICES Managing Strategic Transitions : Managing Strategic Transitions A movement from one level of socio-technical system to another. Often required when adopting strategic systems that demand changes in the social and technical elements of an organization. Questions Managers Should Ask : Questions Managers Should Ask Forces at work in the industry and strategies Using information and communication technology The direction and nature of change within the industry Opportunities to be gained by introducing information systems technology Kinds of systems are applicable to the Being behind or ahead of the industry in its application of information systems The current business strategic plan, and the cur­rent strategy for information services Sufficient technology and capital to develop a strategic information systems initiative The greatest value to the firm Challenges : Challenges Integrations Sustainability of competitive advantage
