Role design and job descriptions for Wire EDM Shops: who decides paths, settings and first-piece sign-off
When a programmer, operator and setter all think they decide the settings, parts are scrapped and people blame each other. Clear roles say who does what and who has the last word.

Share your requirementsWhy role design and job descriptions matters in wire EDM shops
In a wire EDM shop, titles often hide the real work. The operator has been tuning parameters for years but the programmer says only they can change them. A setter fits the fixture but nobody has written who checks it. When a cut goes wrong, each person has a reasonable story, and the argument takes longer than the repair.
Good role design writes down, for each position, what the job is for, what the person decides alone, what needs approval and what they hand to others. It names the limits on parameter changes, who signs the first piece and who may start an unattended run. Descriptions are short, used in hiring and appraisals, and match what people really do.
How to set it up
1. Watch the work for a week
Walk the floor and note who really decides paths, fixtures, parameters, first-piece checks and overnight starts. Write what happens, not what the old title says.
2. Draft each role on one page
For each role write the purpose, the main tasks, the decisions the person makes alone and the ones they must ask about. Keep language plain so operators read it.
3. Set limits for parameter changes
Agree which settings an operator may adjust and by how much, and what must go back to the programmer. Write it near the machine. See role design for a template.
4. Link roles to the skill ladder
Show how an operator moves to a setter or programmer, and what they must prove. This gives helpers a path and gives you a way to choose for each opening.
5. Use the descriptions straight away
Share them with the team, use them in the next hire and the next review, and fix what the floor says is wrong. A role page that is never used soon goes out of date.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- List the last three scrapped parts and who was said to be responsible for each.
- Ask the programmer and the operator separately who may change cut settings and compare answers.
- Check whether any job description in your files matches the work a person does today.
- Count roles held by one person alone with no named backup.

Questions owners ask
Yes, short ones. Even with a few people, unclear limits cause scrap and quarrels. One page each is enough if it says who decides what.
In small shops one person often does both. If so, write both sets of tasks and name a second person for each, so the shop is not stuck when that person is away.
Review them when you hire, promote or change a machine, and once a year otherwise. Keep them short and keep the file somewhere the supervisor can find.
