Exam-style question
Try this first
Explain why a design for a software project should be presented with sufficient clarity for a third party to understand it. In your answer, discuss how a suitable combination of diagrams, prose, algorithms or pseudo-code, data structures, database relations, technical description languages, and interface screenshots can contribute to that understanding. Refer to the task when deciding which forms of communication are appropriate.
Model answer
What a good answer should say
- The design should be clear enough for a third party to understand the structure of the proposed solution and the things on which it relies.
- This makes the intended approach communicable rather than leaving important decisions implicit.
- Diagrams can show components, relationships, or flows, while prose can explain the meaning of those diagrams and clarify decisions that are not easily represented visually.
- Algorithms or pseudo-code can describe important processing without requiring the reader to interpret complete program code.
Explanation
Why this works
Credit should be given for explaining the purpose of clear communication, linking specific design methods to what they communicate, recognising that the combination depends on the task, and identifying relevant dependencies such as libraries, databases, or frameworks. The answer should focus on design communication rather than implementation detail alone.
