Role design and job descriptions for Food Ingredient Makers: weighing, blending and lab roles
In an ingredient plant a wrong weight spoils a lot and a vague role hides who approves what. Role design names who weighs, who checks, who releases and who talks to the customer.

Roles grow by habit. The weighing operator also fills drums when short of hands, the analyst also does the batch paperwork, and the senior chemist answers customer calls. Nobody can say who may release a batch or who signs a changeover clean. When a customer finds a problem, each person points at another. New hires are given a title and a list of tasks that does not match what the person next to them does.
Where roles are designed, weighing is a protected role with a calm area, a double check on small components and a sign-off. The batch record has a named owner for each line. The lab has a clear release authority, and technical service staff know what they may promise and what they must pass to the plant. Each role has a one page description that both the person and the supervisor have read.
How to set it up
1. List what actually happens in a day
Follow a weigher, a blender, an analyst and a technical service executive for half a day each. Write the tasks they do, not the title on the door.
2. Separate the tasks that must not mix
Decide where weighing, checking and releasing need different people. Note where cross-cover is safe and where it is not.
3. Write a one page description for each role
Purpose, main tasks, who they report to, what they may decide, what they must pass up. Keep it to plain sentences, in the way set out under role design and job descriptions.
4. Name the authority for batch release and changeover
Write down who signs the batch record, who releases the lot and who confirms a clean between products, and post it where people work.
5. Review with the people in the role
Read each description aloud with the person in the role. Fix what does not match reality and agree a date to review it again.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Ask three weighing operators what they do in a day and compare it with the written duty.
- List who can release a batch and check each is named in a written role.
- Find a task that two roles both think belongs to the other and note it.
- Check whether technical service staff know what they may promise a customer without asking the plant.

Questions owners ask
It depends on your size, but release authority should not sit with the person under output pressure. Many plants have the lab report to a head of quality or the owner.
Yes, kept short. A weighing operator should be able to read in a few lines what is expected, what to check and when to stop and call someone.
One page is enough. List purpose, tasks, decisions and limits. Long documents are not read, and a short one that matches the work is used.
