Prototype-First Delivery
Prototype Before You Document: When a Walkthrough Beats a 40-Page Business Requirements Document
Documentation is useful after the team understands the problem. Before that, a prototype can reveal misunderstanding faster than another review meeting.
A prototype changes the conversation
Stakeholders react differently when they can see and touch a workflow. Abstract agreement often breaks when a screen, state, or exception path appears.
That reaction is valuable. It exposes ambiguity early.
The prototype does not replace analysis
Prototype-first does not mean skipping requirements. It means using a lightweight working model to improve requirements quality.
The delivery practitioner still needs decisions, acceptance criteria, data rules, and release constraints.
Use it for risky assumptions
Prototype the part people keep debating, misunderstanding, or hand-waving: onboarding, payment exception, approval flow, support queue, or dashboard interpretation.
Do not prototype everything. Prototype the uncertainty.
Document after learning
Once the walkthrough exposes decisions, update the backlog, criteria, decision log, and workflow documentation.
That sequence produces better documentation because it is grounded in observed stakeholder reaction.
Why this matters now
AI-assisted tools make prototype-first discovery cheaper and faster, but judgment still decides what to build and what to ignore.
That is the balance CatalystAgile is trying to show.
