Quick answer
Professional project documentation — SRS, UML diagrams, test cases, and a structured report — often contributes 30–40% of your grade. Clear writing, consistent formatting, and traceability from requirements to implementation impress evaluators and viva panels.
Documents every engineering project needs
- Software Requirements Specification (SRS)
- System architecture and ER / UML diagrams
- Module design and API documentation
- Test plan and test case results
- User manual and deployment guide
- Final project report and PPT
Common documentation mistakes
Screenshots without captions, mismatched diagram notation, copy-pasted generic text, and no link between requirements and features are the fastest ways to lose marks. Start documentation in parallel with development, not the week before submission.
