Most projects die in the gap between "here is the idea" and "here is the spec." The workflow lives in your head, the edge cases live in three other heads, and a staffing shop quotes you for a build that nobody has actually seen yet. A proposal is a guess with nicer formatting.
Why a prototype beats a proposal
A prototype is the cheapest way to find the thing nobody mentioned in the kickoff: the approval step, the weird export, the one client who does everything backwards. We would much rather find that in week two of a sprint than in month four of a build, when it has friends and a mortgage.
How four weeks actually runs
- Week 1: we play the workflow back to you until we both agree on what it really is.
- Week 2: the spine gets built, the screens and the data shape.
- Week 3: AI goes in where it earns its place, with guardrails and a few good examples.
- Week 4: we harden the demo, write the delivery plan, and hand it over.
What you walk away with
- A working prototype on real example data, not a clickable mockup.
- A scoped delivery plan in phases, in the order we would ship it.
- An integration map of the systems it touches and where the hard parts are.
- A build estimate you can take straight to a budget conversation.
When to skip it
If your requirements are already nailed down and will not move, skip the sprint and let us just build the thing. The sprint is for when the workflow is real but still a little blurry, which, in my experience, is most of the time someone picks up the phone.
