STAGE 03 · FEASIBILITY
Build the right prototype
Build only what is needed to answer the highest-risk technical, clinical, and usability questions.
RECOGNIZE THE STAGE
How to know you are here
A physical, digital, or hybrid prototype exists
The prototype is being used to answer defined feasibility questions
Major technical and use-related risks remain open
READINESS LENSES
What must be managed together
Bench feasibility, simulated use, engineering characterization, and early usability evidence.
Use the pathway and risk assumptions to guide materials, software, testing, and documentation.
Pre-seed · accelerators · SBIR/STTR. Often $100K–$1M.
ACTION PLAN
Priorities for the next 90 days
- 01
Define the question and acceptance criterion for every prototype
- 02
Run representative bench and simulated-use testing
- 03
Begin the risk file and trace important design decisions
- 04
Separate proof-of-principle features from commercial requirements
BEFORE YOU ADVANCE
Required outputs
- Prototype build and test records
- Feasibility evidence package
- Preliminary hazard analysis
- Early usability findings
WATCH FOR
Common failure modes
- Polishing a prototype instead of retiring risk
- Uncontrolled iteration with no design history
- Testing in conditions that do not represent actual use
THE DECISION GATE
Does the core mechanism work reliably in representative conditions, with manageable risks?
Do not advance because time or money has been spent. Advance when the evidence supports the decision.
