Say in the proposal how you will know the project worked

Decide the evaluation now, not at the end. For each objective, write how you will check it:

• Functional: test cases for each must feature, run before every evaluation.
• Performance: a measured number, such as response time under a stated load, or model accuracy on held-out data.
• Usability: a short test with real users from your stakeholder list, with tasks and a simple questionnaire.
• Comparison: for a research project, the baseline you will beat or match, and the dataset you will use.

Planning evaluation early changes how you build: you collect the right data, log the right events and recruit test users in time. Leaving it to the final month usually means the results chapter is thin.
