🔹 Activity B – Short Answer Practice (2–4 marks each)
(Section B format — applied understanding)
1. Define the term functional requirement and provide one example.
2. Define the term non-functional requirement and provide one example.
3. Describe one reason why constraints must be identified before development begins.
4. Explain how economic constraints can influence the scope of a software solution.
5. Identify two differences between functional and non-functional requirements.
6. Explain why it is important to clearly define both what a solution will do and what it will not do.
🔹 Activity C – Scenario Application (3–6 marks each)
(Section C / SAT-style applied reasoning)
Scenario 1 – School Library App
A developer is designing a web application that allows students to view library opening hours and reserve books online.
- The app must work on phones, tablets and laptops.
- The client requires the solution to be completed within six weeks.
- Students must log in using their school credentials.
- The solution will not allow book renewals in this version.
Tasks:
- Identify one functional requirement.
- Identify one non-functional requirement.
- Identify one constraint and describe its impact on the project.
- Outline one element of the scope of this solution.
Scenario 2 – Local Business Ordering System
A small café wants a system to record daily orders, print receipts, and track inventory. It must use existing Windows hardware and be developed by one staff member.
Tasks:
- List two constraints that will influence this project.
- Identify one functional requirement and one non-functional requirement.
- Suggest one feature that would fall outside the scope of the solution, and explain why.
🔹 Activity D – Extended Response (6–8 marks)
(Analytical / Evaluation task — Section C format)
Prompt:
Discuss how clearly defining solution requirements, constraints and scope contributes to the success of a software project.
In your response, refer to at least two examples of constraints and their influence on functional or non-functional requirements.
