Preparing for a Systems Analysis and Design (SAD) exam can feel like trying to build a bridge while people are already driving across it. It is a discipline that requires a balance of technical logic and people skills. To help you sharpen your skills, we have compiled a set of high-impact revision questions and answers that tackle the core concepts of the Software Development Life Cycle (SDLC).

Key Revision Questions
1. What is the fundamental difference between Systems Analysis and Systems Design?
Many students get these two confused, but the distinction is simple:
Systems Analysis is the “what” phase. It involves studying the current system and identifying what the new system should do to meet user requirements.
Systems Design is the “how” phase. It focuses on the technical implementation—defining the architecture, modules, interfaces, and data for a system to satisfy specified requirements.
2. Why is the Feasibility Study considered the most critical part of the SDLC?
Without a feasibility study, a project is essentially flying blind. It determines if the project is even worth pursuing. Analysts look at:
Technical Feasibility: Can we build it?
Economic Feasibility: Is it worth the cost?
Operational Feasibility: Will the users actually use it? If a project fails any of these tests, it’s better to stop before burning through a massive budget.
3. Explain the “Waterfall” model vs. “Agile” methodology.
The Waterfall model is linear and sequential; you finish one phase entirely before moving to the next. It’s great for projects with fixed requirements.
Agile, on the other hand, is iterative. You build the system in small increments (sprints), allowing for constant policy-page-at-mpya-news/" title="Feedback">feedback and changes. In the modern tech world, Agile is often preferred for its flexibility.
4. What role do Data Flow Diagrams (DFDs) play in the analysis phase?
A DFD is a graphical representation of the “flow” of data through an information system. It doesn’t show the logic or the timing; it simply shows where data comes from, where it goes, and how it’s stored. It is a vital communication tool between the analyst and the stakeholders.
Expert Tips for Your SAD Exam
Understand the Users: Most system failures aren’t technical; they are social. Focus on how the system manages user requirements.
Keywords Matter: When answering questions, use industry terms like Scalability, Prototyping, and Legacy Systems.
Draw Diagrams: If a question asks for a process, a quick sketch of a Gantt chart or a Use Case diagram can often earn you extra marks for clarity.
