Role design and job descriptions for Investment Casting Foundries: one page per role, wax to inspection
Lost wax work moves through many stages, and when roles blur, errors have no owner. Clear role sheets name what each person controls, checks and hands over.

In a short-run foundry with many part numbers, people drift into each other's work. A wax assembler corrects dies, a shell dipper adjusts slurry, an inspector sorts parts that should have been stopped earlier. The titles on paper say little about who is responsible for what, and the floor runs by habit. When a customer complaint arrives, nobody can say whose stage it was.
A role sheet is a single page per role. It lists the purpose of the role, what the person controls, what they check before handing on, what they record and who they report to. For a pourer it may include temperature checks, shell preheat, pour log and handover note. For an inspector it includes how to stop a batch and who to tell. The sheet is short enough to be used in coaching and hiring.
How to set it up
1. List the stages and handovers
Draw the path from wax to dispatch on one page and mark each handover point. Roles are easier to describe once you can see where one person's work becomes another's.
2. Write purpose and controls for each role
In two or three lines, state why the role exists and what the person decides without asking. Avoid long lists of tasks. Focus on the things that decide quality and safety.
3. Add checks and records
State what the person checks before passing work on and what they write down, such as wax weight, dip count, shell dry time or pour temperature. Keep the list to what is genuinely used.
4. Set stop and escalation rules
Say who can stop a batch and who they tell. Inspectors and pourers especially need this written, so stopping is not seen as defiance. Role design support can turn this into a template.
5. Test the sheets on the floor
Give each sheet to the person and their supervisor, ask if it matches reality, and correct it. Use the final versions in hiring, onboarding and reviews.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Ask three people in different stages what they are accountable for and compare the answers
- Look for jobs where two roles both correct the same defect
- Check whether any person is doing work well outside their stated role regularly
- Count how many roles have a written description that the person has actually seen

Questions owners ask
Yes, but short ones. A single page per role is enough. The point is clear stage ownership, so that a defect leads to a fix and not an argument.
Describe the core role first, then list the extra stages they cover as named secondary duties. Record cover skills in a skill map so you know who can step in and who is stretched too thin.
Not necessarily. Fix the content first. Change titles only where they mislead, such as one title covering both a trainee and a senior. Title changes can raise pay expectations, so plan them with care.
