The Value of Prototypes
summary
Shows how a quick 20-hour prototype — a small semi-functional UI with hardcoded values and static validation — uncovers mismatched requirements and coaching opportunities, turning an example 160-hour rework cycle into about 120 hours by catching issues early. Recommends lightweight mockups or front-end stubs instead of perfect code, mentions Figma or quick front-end mockups and Zulip for feedback. Skip prototypes for single-developer work, tiny tweaks, or when no business reviewer exists.
