Production readiness score
Fifteen questions across the six areas that stall hardware launches. You get a 0–100 score, the build stage your answers actually support, and your top three risks, each with a next action.

How the score works
Each answer maps to a value from 0 to 1 (the full breakdown under your result shows every one). An area score is the weighted average of its answers. Weights run from 1.0 to 1.5 and reflect how often that gap derails a launch in our experience; they are our judgment, not a published standard. The overall score is the plain average of the six areas. Your stage is the lower of the build you said you're on and the stage your score supports (Concept under 25, Prototype 25+, EVT 45+, DVT 65+, PVT-ready 82+ and at least a DVT build). The top risks are your three largest weighted gaps.
This is an estimate to help you prioritize, not an audit, and not legal or compliance advice. Have an engineer review anything you're about to spend tooling or production money on.
How srvo helps with this
We close the gaps between prototype and production.
One team for the mechanical, electrical and firmware work that turns your top risks into a production plan.

Bring-up, firmware and factory test
Board bring-up, update paths, test plans and end-of-line test stations. Firmware & electronics
Ready for the lab
Design choices that pass pre-compliance the first time, and a certification plan before DVT. Certification map
FAQ
Questions founders ask
What do EVT, DVT and PVT mean?
They are the three validation builds between a working prototype and mass production. EVT (engineering validation test) is the first integrated build on your own electronics, to prove the design works. DVT (design validation test) uses production-intent parts, often from production tooling, and is where reliability, environmental and certification testing happen. PVT (production validation test) is built on the real production line, with production fixtures and processes, to prove the line can make the product at yield.

Is this a standard or a certification?
No. It is srvo's rubric, written by engineers, to help you see gaps early. It is an estimate, not an audit. Use it to decide what to look at next, and have an engineer review anything you are about to spend tooling money on.
What happens to my answers?
Your answers are encoded in the page link (the part after #) so you can share them with a cofounder. We record anonymous usage analytics, including your overall score, to improve the tool. We only get your email if you choose to send your result.
My score is low. Is that bad?
Not on its own. A low score at the prototype stage is normal. What matters is sequencing: the risks are ordered by impact, so fix them in that order before you spend on tooling or a production order.
