Role design and job descriptions for API Manufacturers: clear roles for blocks, labs and quality
An API plant splits work among blocks, labs and quality teams that depend on each other. Clear roles show who fills, who checks and who signs, so records are right the first time.

Where roles are loose, a block operator fills a record, a supervisor skims it and a QA reviewer assumes the earlier checks were done. When an entry is wrong, each party points to another. The analytical lab and the plant work on different clocks, and nobody owns the gap when a sample waits. Block heads are given more tasks than they can handle because their role is just a title.
Good role sheets are short and specific. They name the batch record entries the person fills, the checks they make, what they sign and who they hand over to. For block heads, the sheet lists the staff under them, the scheduling task and the escalation rule. For the lab, it states the sample turnaround that plant staff can rely on.
How to set it up
1. Trace one batch from start to release
Follow a recent batch through blocks, lab and QA. Note who touched each step, who checked it and who signed.
2. Write a sheet per role
List what the person fills, checks and signs, who they hand to, and what they escalate. Keep each sheet to a page.
3. Agree sample turnaround with the lab
Set a plain expectation, such as how soon a sample is tested, so the plant can plan. Let both sides challenge it.
4. Review with the people who do the job
Ask operators, analysts and QA reviewers to mark what is wrong or missing. Use the sheets in recruitment and in reviews.
5. Keep a change note for each sheet
When the process changes, update the sheet and tell the people affected. Date each version so staff know which is current.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Count record errors in the last quarter that had no clear owner.
- Ask two block heads what they are accountable for and compare answers.
- Check how long samples wait before testing and who is waiting.
- List roles that exist only on a notice board with no written sheet.

Questions owners ask
The staff in the block, the daily schedule, the first check on records and the escalation of problems. Write it down so it is not just a title.
One page is enough. It should name entries, checks, signatures and handovers in plain words. Anything longer will not be read on the floor.
Yes. A shared view of turnaround and who chases a late sample reduces friction between the two teams on every batch.
