The Concept Decision Sprint
Four weeks. One decision paper.
The three concepts actually worth your money.
The Concept Decision Sprint runs your entire concept portfolio through the Napkin Protocol, Napkin Dump to Napkin to Line, in four weeks, with engineers and designers in the room from day one. Not analysts. People who can tell you whether users can and will actually use the product and whether the mechanism survives contact with a mold.
Four deliverables, not just a slide deck.
A Decision Paper
A decision paper shortlisting 2–3 concepts, each with technical feasibility evidence, an early usability read, manufacturability notes, and rough cost and timeline estimates.
Evidence Presentation
A steering-committee-ready presentation of the evidence, so the decision runs on data, not on whoever argues loudest.
Engineering prototypes
You will get all ideas generated, the refined concept drawings, and the prototypes and CAD-files made to explore and support the decision.
Kill Criteria
Pre-agreed kill criteria your organization keeps forever.
If The Wipe shows that none of your current concepts should proceed, we tell you in week two, and you pay 40%. We’d rather kill your project cheaply than build it expensively.
A proven process to explore, define, test and make concept decisions.
One week per step of the Napkin Protocol →
Napkin Dump
Everything on the table, unfiltered. Broad concept generation across your organization, engineers, sales, clinicians, users, whoever has a stake in the outcome. Volume and honesty first.
The Wipe
Pre-agreed criteria, technical realism, regulatory complexity, market size, strategic fit, cut the list down. This is the week you’d pay 40% and stop, if nothing survives it.
Fold Test
Rapid pre-validation on the survivors: refined concept drawings, engineering prototypes, CAD, expert interviews, feasibility checks, and an early usability read.
Napkin to Line
Everything synthesized into the decision paper and the steering-committee evidence presentation, with kill criteria your organization keeps for the next decision too.
