Short answer: A startup should do a DFM review before final engineering release, before mold tooling and again before pilot production.
Best timing
- After the product requirements are clear
- Before committing to mold tooling
- Before approving first samples
- Before scaling production volume
Reason
DFM is most valuable while design and supplier decisions can still change without major cost.
