Role design and job descriptions for Precision Component Makers: who owns quality, from operator to inspector
In a precision unit the operator, the inspector and the quality engineer all touch the same part. If their roles overlap or leave gaps, a rejection becomes a dispute about who should have caught it.

Job descriptions in many small precision units are a title and a pay band. The operator thinks the inspector will catch errors. The inspector thinks the operator should not have passed the part to him. The quality engineer is pulled onto the floor and then onto customer calls. A customer complaint is answered by whoever picks up the phone, and the lesson is lost.
Good role design here is plain. For each seat, what it measures, what it may release, what it must escalate, and who covers it when away. The operator owns the in-process checks and stops the machine. The inspector owns release and records. The quality lead owns the customer response and the root cause. Written down, the roles also define how people grow.
How to set it up
1. Map the flow of one part
Trace a typical part from material receipt to dispatch and mark each check, record and decision. This shows where the roles touch.
2. Write each role on one page
For operator, setter, inspector, quality engineer and quality lead, list what the seat does, measures, may release and must escalate. Use role design and job descriptions as the format.
3. Define who stops the line
State plainly who may stop a machine and hold a lot, and that no one is blamed for a justified stop. Print it where the floor can read it.
4. Name a cover for each seat
For each role, name the person who covers absence and what they may not do alone, such as releasing a lot on a new customer part.
5. Test the roles on a real rejection
Take the last customer rejection and trace who did what against the new descriptions. Adjust the wording where a gap appears.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Take the last customer complaint and see who answered it and whether that was their role.
- Ask three operators who may release a lot and compare the answers.
- Check whether each inspector has a written scope of what they can release alone.
- Count seats with no named cover.

Questions owners ask
Both, at different points. The operator owns checks during the run and the right to stop. The inspector owns release and records. The quality lead owns root cause and customer reply. Write it so no seat is empty.
One page that the person can read and use. List tasks, decisions they may make, checks they own and who they report to. Long documents are filed and forgotten.
They show that people know their part, but only if the floor behaves as written. Make sure the descriptions match the practice before an audit, not after.
