The evaluation stage of software development requires the client and developer to review the software to determine if it meets user requirements and is fit for purpose. They evaluate the software against criteria like robustness, reliability, portability, efficiency and maintainability. The software should be evaluated at all stages of development by the client and developer, not just at completion.

1. Evaluation

2. Evaluation
The evaluation stage of the software development process
requires the client and developer to review the software.
Broadly speaking, they evaluate against the following
questions:
1. Does this software meet the user
requirements?
2. Is it fit for purpose?

3. Evaluation - criteria
To answer these questions, the original aims of the
software must be evaluated against the following
criteria.
1. Robustness
2. Reliability
3. Portability
4. Efficiency
5. Maintainability

4. Evaluation - when
The software should be evaluated by client and developer
at all stages in the process, not just when the software is
complete.
e.g.
 How well the client’s problem has been understood
should be evaluated at the analysis stage
 The HCI should be evaluated at the design stage
