Design & DFM
Does the structure suit the intended process?
Prototype to Production
A working prototype is a starting point, not a production release.
Your starting point
For teams with an existing prototype or design that needs a practical route to stable manufacturing.
Key decision: proceed, revise or hold?
A production release should be based on agreed evidence. Tooling expenditure and a good-looking sample do not by themselves demonstrate a stable manufacturing process.
A working prototypeA function or design
A function or design
has been demonstrated.
The prototype may have answered its intended question. Record which materials, processes and conditions it represented.
Repeatable productionThe result needs
The result needs
to hold across builds.
Manufacturability, supply, assembly, cost and quality need to work together under production conditions.
What needs to be ready?
Materials & components
Are specifications suitable for repeat supply?
Tolerances & assembly
Can parts fit and assemble consistently?
Tooling
What tools or fixtures are needed, and how will they be verified?
BOM & documents
Is manufacturing information complete and consistent?
Suppliers & processes
Do capability and quality requirements align?
Pilot production
Which questions need a representative trial?
Quality & repeatability
What evidence supports the next release decision?
Areas to evaluate according to the product. They are not a mandatory service package or an assumption that every prototype needs redesign.
Illustrative engineering situations · not client case studies
The decision depends on the gap.
- CNC prototype → molded part: review wall sections, draft, tolerances and fastening for the intended production process.
- Hand-fitted assembly → repeat build: review location features, tolerance relationships and assembly sequence.
- Prototype material → repeat supply: assess an available alternative and verify the required performance.
What is actually proven?
Review the prototype revision, how it was made and what was tested. Identify production materials, interfaces, tolerances and conditions that the prototype has not demonstrated.
What must change before tooling?
Prioritize DFM and engineering changes by risk. Agree which dimensions, materials and assembly decisions must be fixed before tooling commitments, and which uncertainties need another targeted trial.
What must a pilot demonstrate?
Define the production-representative build, inspection and test criteria. Review first parts, assembly sequence, recurring defects and process variation. A pilot should produce evidence for a release decision, not merely a batch of samples.
What allows repeat orders?
Close high-priority actions, record the approved revision and reference samples, and assign ongoing inspection and change control. Where criteria are not met, document the remaining work before increasing volume.
What to bring
- Existing CAD, BOM and prototype or sample
- Known test results and unresolved issues
- Target volumes, timing, materials and use conditions
Outputs to define together
- Production-readiness gap review
- DFM and engineering change priorities
- Tooling and pilot acceptance criteria
- Pilot findings, action closure and release recommendation
