The fastest way to go from idea to live feature without getting stuck in endless docs or delays.

This SOP is built from the ground up while redesigning a complex SaaS product (Heatmap), but it’s flexible enough for any product team. The goal is speed with clarity: just enough structure to keep the team aligned, without slowing down the move from concept to code.

You’ll notice that every step is biased toward action. We assume you won’t always get a perfect brief, you won’t always have time for polished research, and you definitely won’t have patience for bloated documentation. Instead, this process shows you how to write your own quick brief, test designs against simulated users with GPT, run lightweight external user tests, and deliver a clean dev handoff — all in a way that’s simple, repeatable, and fast.

Follow the steps, use the built-in GPT prompts where provided, and by the end of this process you’ll have designs that are tested, validated, and ready for dev to build with confidence.
