Design Documentation

Summary

Writing down the reasoning behind design decisions, not just the decisions themselves — protects institutional knowledge and helps future designers (including future you) understand why something is the way it is.

• 1Write a short design rationale doc for one of your practice projects.
• 2Learn why documenting rejected alternatives (and why they were rejected) is often as valuable as documenting the final choice.
• 3Practice keeping documentation concise — a few clear paragraphs beats a wall of text nobody reads.
