- 3. Need for an information system strategy Due to the multitude of technological developments over the past two decades many areas within an organisation can now take advantage of cheap user-friendly processing power. Information needs of users have increased and can be met in many different ways. To prevent the proliferation of unique independent information systems developing within an organisation, an overall information system strategy needs to be considered.
- 4. IS needs an effective strategic plan Because IS consumes a portion of the organisation’s finite resources IS must accommodated rapid technological changes IS must enable the business to function effectively Therefore, IS strategy will ensure that IS will cost effectively deliver strategic systems.
- 5. Aims of the IS strategic plan Clearly identify where IS is going within the organisation therefore avoiding the dangers of taking actions that do not contribute to the overall mission Provide a formalised set of benchmarks so that progress of the plan can be monitored.
- 6. The information system strategy The information system strategy is derived from the business strategy which itself is evolved from the strategies of all the sub-systems. Once an information strategy has been decided upon EG. providing a better service or information to the customers about an organisations products, then a tactical plan for setting up the system can be devised. This will include, where it will be located, what hardware and software will be used, what training is required. Although it is necessary to consider the information sub-system as an integral part of the overall business system, it is also important to consider it in its own right. That is, the information sub-system must be concerned with new techniques and technologies which could benefit the organisation. All business strategies must be responsive to the external environment

- 8. Elements of a strategic plan A clear statement of IS objectives – where they want the business to be An inventory and assessment of both the current organisational capabilities and problems resulting from current practises – where the business is now An implementation plan identifying long-term and short-term actions and allocation of resources – how to get to where they want to be
- 9. Elements of IS strategy (Ward &Griffiths, 96) Business information strategy . This defines how information and knowledge will be used to support the business objectives IS functionality strategy . Defines the requirements of the business from the systems. Defines how the resources will be used and the allocation of responsibility IS/IT strategy. This defines the hardware and the software standards and preferred suppliers.
- 10. IS/IT strategy Determines the technological infrastructure of the organisation This ensures Appropriate technologies used Standards are set In terms of costs, efficiency and supporting business users, customers and others Determines how IT is applied within the organisation Ensures that IT supports the business strategy Ensures that the resources are made available
- 11. Organisation environment All organisations operate within an environment Micro-environment – immediate includes customers, suppliers and intermediaries Macro-environment – wider environment of social, legal, economic, political and technology The environment influences the way in which the organisation works
- 12. Seven R’s of strategy (Lickert, 97) These are ways in which organisations can compete, using information system strategy to respond to its external environment Reach Reaction Responsiveness Refinement Reconfiguration Redeployment Reputation
- 13. Strategy process model 1 Strategic analysis 2 Strategic objectives 3 Strategic definition 4 Strategic implementation Monitor, evaluate and respond

- 17. To Summarise Before the tactical planning of information systems is carried out, the overall information system strategy must be agreed upon and communication to all other sub-systems. This strategy will identify areas within the business strategy that would benefit from new or improved information systems. It will map out a plan for the development of these systems based on strategic importance and availability of resources. It will incorporate new developments in technology and future needs. It will also decide between a policy of centrally-controlled development of systems or a strategy of local development to meet local needs.
