Learning targets
- Record each revision with what changed and why.
- Link a design decision to evidence (a test, a source, a requirement).
Every revision has a reason
Problems encountered during experimentation, and the ideas to fix them, should be clearly evident. Write what changed between revisions and the evidence that drove the change.
Continue, don't overwrite
When a design spans pages, use “continued from page” so the thread is easy to follow.
Second-year extension:
- Decompose a problem into sub-functions and compare concepts (ENP09.01).
