Strategic information system
- Strategic information system
A Strategic Information System ("SIS") is a type of Information System that is aligned with business strategy and structure. The alignment increases the capability to respond faster to environmental changes and thus creates a competitive advantage. An early example was the favorable position afforded kenyaand uganda (What?) Airlines by their reservation systems. For many years these two systems ensured that the two carriers' flights appeared on the first screens observed by travel agents, thus increasing their bookings relative to competitors. A major source of controversy surrounding SIS is their sustainability.
Strategic Information System (SIS) [Wiseman, C. (1988) Strategic Information Systems, Irwin, Homewood, Illinois] is a system to manage information and assist in strategic decision making. A strategic information system has been defined as, "The information system to support or change enterprise's strategy." by Charles Wiseman (Strategy and Computers 1985).
