Exam-style question
Try this first
A student records dialogue with intended users and uses it to identify nearly all of the system's required functionality. They document specific objectives, most of which are measurable and appropriate, and provide a problem model that can be used in later design. One minor requirement is omitted. Evaluate this analysis against the three levels and justify the most appropriate mark range.
Model answer
What a good answer should say
- The most appropriate level is level 2, with a mark in the 4-6 range, because the analysis is well scoped and the model is sufficiently useful in subsequent stages.
- Most requirements are documented in a set of mainly measurable and appropriate specific objectives, and the requirements were arrived at in the main through dialogue with intended users.
- However, one omitted requirement means that the analysis does not fully cover all required functionality, so level 3 is not the best fit.
- If the omitted requirement were added and the analysis became fully or nearly fully scoped, it could meet level 3 requirements and be considered for 7-9 marks.
Explanation
Why this works
Level 2 explicitly allows some omissions that are not serious enough to undermine later design. The user dialogue, objectives, and useful model are strengths, but incomplete coverage prevents the analysis from clearly meeting level 3.
