Exam-style question
Try this first
A team is planning a solution as several modules. Describe how clear documented interfaces can support the design of the modular structure, and explain how an iterative approach could improve that design.
Model answer
What a good answer should say
- Clear documented interfaces describe how the modular parts are intended to connect and work together.
- This helps the team design an appropriate modular structure and gives each part a clear relationship with the others.
- The team can then use an iterative process to review and refine the structure.
- For example, a prototype or agile development cycle could reveal that modules need to be reorganised or that their interfaces need clarification.
Explanation
Why this works
The answer should link documented interfaces with the design of modular parts and explain that iteration allows the design to be reviewed and refined. References to prototyping or an agile approach are relevant because the specification explicitly recognises these as ways design can be iterative.
