JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD B.Tech IV MANAGEMENT INFORMATION SYSTEM Previous Question Paper (September - 2022 - R16)

The Information Systems Strategic Grid, developed by McFarlan and McKenney, is a framework used to assess the strategic impact of existing information systems and the potential impact of future applications on a firm's business strategy. It classifies IT applications into four quadrants based on their current and future importance:

1. Support: Applications that are essential for operations but do not provide a competitive advantage (e.g., payroll, email). Failure here causes operational disruption, but success does not differentiate the firm.
2. Factory: Systems where the business is highly dependent on IT for current operations, but new developments are not critical for future competitive advantage (e.g., manufacturing control systems). Downtime is catastrophic.
3. Turnaround: Applications that are not critical for current operations but are vital for future competitive success. These are high-priority areas for investment to gain market advantage.
4. Strategic: Systems that are critical for both current operations and future competitive advantage. These are the core of the business strategy and require significant management attention and investment.

Information systems are categorized based on the organizational level they serve and the specific management functions they support:

• Transaction Processing Systems (TPS): Record and process daily routine transactions (e.g., sales orders, payroll) at the operational level.
• Management Information Systems (MIS): Provide middle management with reports on current performance and historical data to monitor and control business operations.
• Decision Support Systems (DSS): Focus on semi-structured or unstructured decision-making by combining data and analytical models to solve specific problems.
• Executive Support Systems (ESS): Designed for senior management to address strategic issues and long-term trends through high-level summaries and external data.
• Expert Systems/Knowledge Management Systems: Capture and distribute organizational knowledge or mimic human expertise to solve complex domain-specific problems.
