Exam-style question
Try this first
A student analyses a real problem for a proposed system. They list three broad aims: make the system useful, make it simple, and include the important features. They do not record dialogue with intended users, do not identify all required functionality, and provide no model of the problem. Using the marking criteria, explain the likely level and mark range for this analysis. State what would need to be improved to reach level 3.
Model answer
What a good answer should say
- The analysis is most likely to be placed at level 1, in the 1-3 mark range.
- It is only partly scoped, and its aims are not sufficiently specific, measurable, or appropriate as documented objectives.
- It does not cover all required functionality, does not show that requirements were obtained by considering the needs of intended users through dialogue, and does not model the problem.
- To reach level 3, the student should fully or nearly fully scope the real problem, document measurable and appropriate specific objectives covering all required functionality, use dialogue to consider intended users' needs, and provide a problem model that will be useful in subsequent stages.
Explanation
Why this works
The evidence matches the level 1 description because the analysis is partial, the objectives are broad rather than measurable and specific, user needs are not considered through dialogue, and the problem is not modelled. Level 3 requires all of these areas to be addressed substantially.
