Assess an Engineering Change

Trace a connector-width change through interface clearance, testing, stock, and customer configurations before choosing a release decision.

Choose one answer

A connector changes from 12.0 ± 0.1 mm to 12.4 ± 0.1 mm. Housing clearance falls from 0.3 mm to 0.1 mm, below the 0.2 mm fit minimum, and insertion force rises from 18 N to 27 N against a 25 N test limit. Approve, reject, or defer?

Defer pending housing, fit-test, stock, and customer-configuration verification.Release it: only one part changes and its tolerance of ±0.1 mm stays the same.

Show a hint

Check 0.1 mm against 0.2 mm and 27 N against 25 N. Then ask which owners must close those failed checks.

About this activity

What you practise: Review a second synthetic change with one pass, one watch, and one fail condition; map the dependency owners and choose approve, reject, or defer with evidence.

A connector changes from 12.0 ± 0.1 mm to 12.4 ± 0.1 mm. Housing clearance falls from 0.3 mm to 0.1 mm, below the 0.2 mm fit minimum, and insertion force rises from 18 N to 27 N against a 25 N test limit. Approve, reject, or defer? The connector widens from 12.0 to 12.4 mm. Housing clearance drops from 0.3 to 0.1 mm; the minimum is 0.2 mm. Insertion force rises from 18 N to 27 N; the test limit is 25 N. 2,400 connectors are in stock and 3 customer configurations use the part. Start at the changed property. Follow every edge to a physical interface, a verification limit, an affected stock item, or a customer commitment before deciding.
