Question 1: System Development Methodology

The assignment asks why a structured methodology is needed for system development and identifies the Critical Success Factors.

Three Critical Success Factors:

1. Standardization of Procedures: A methodology provides a repeatable, predictable process. It ensures that every team member follows the same “roadmap,” reducing confusion and errors.
2. Management Control: By breaking the project into phases (like Planning, Analysis, and Design), managers can set milestones and track progress more effectively.
3. User Involvement: A good methodology ensures that users are consulted at every stage, preventing the development of a system that “works” but doesn’t actually meet the business needs.

Question 2: The Incremental Model

The second part of the assignment focuses on the Incremental Model, where the system is developed and delivered in small pieces (increments).

Characteristics of the Incremental Model:

• Iterative Design: Each increment adds functional power to the preceding increment.
• Priority-Based: The most important features are built and delivered in the first increment.
• Parallelism: Different teams can work on different increments simultaneously once the core architecture is set.

Question 3: Strategic Planning for Information Systems

Often, CS507 assignments from this period ask about the Level of Planning.

• Strategic Planning: Done by top-level management (long-term goals, 3–5 years).
• Tactical Planning: Done by middle management (implementing the strategy, 1–2 years).
• Operational Planning: Done by low-level supervisors (daily/weekly tasks).
