Training path
First weeks
- 1
Plant, process and safety

Plan and attendance
A senior shows how to read the production plan, mark attendance and match people to machines. The joiner prepares a roster for a shift and gets feedback.
- 3
Handover and records
The outgoing supervisor teaches the handover form, what to write and what to say. The joiner completes the form on supervised shifts, and the manager corrects it.
- 4
Quality and rejection basics
The quality head explains the checks, tagging and rework rules. The joiner follows a rejection from detection to decision and writes the steps.
First year

- 3
Downtime and breakdowns

Towards senior

Planning with the manager
The manager brings the supervisor into labour, overtime and maintenance planning, and reviews how the plans worked. The manager reviews afterwards how well the plans held and what the supervisor would change next time.
- 2
Handling performance and discipline
HR teaches fair warnings and record keeping. The supervisor handles a case with HR beside them, and confirms steps with your adviser.
- 3
Finding causes of loss
The supervisor reviews downtime and rejection records for patterns and proposes practical changes. The supervisor reviews downtime and rejection records for patterns, picks the largest causes and proposes two or three practical changes to the manager.
- 4
Developing operators
The supervisor identifies a promising operator, assigns small leadership tasks and gives feedback, and the manager reviews the plan. The supervisor identifies a promising operator, assigns small leadership tasks and gives feedback, while the manager reviews the development plan at intervals.
Performance review
A monthly one-to-one with the production manager using shift records, and a written half-yearly review. Include a visit to the night or weekend shift and feedback from the crew.
What to measure
| Measure | How it is seen |
|---|---|
| Output and plan adherence | Production sheets compared with the plan, reasons for gaps. |
| Quality | Rejection and rework records for the shift. |
| Safety leadership | Toolbox talks, observations, incidents and near-misses. |
| Crew management | Attendance, overtime, grievances and crew feedback. |
| Handover | Whether the next shift supervisor says the handover was complete. |
| Downtime handling | Breakdown records and how fast issues were passed on. |
Evidence to bring
- Shift production sheets
- Handover forms
- Downtime and rejection records
- Safety observations
Questions to ask in the review
- What kept you from the plan this month?
- Which crew members need help and which are ready to grow?
- What was your hardest decision on shift?
- How do you handle a worker who breaks rules?
- What do you lose time on between jobs?
- What do you want maintenance or stores to do differently?
- What safety worry do you have?
- What would you need to become a production manager?
Pitfalls
- Promoting the best operator without teaching how to lead.
- Ignoring night shift in reviews.
- Leaving out fairness and conduct, so favouritism goes unseen.
- Having no handover form, so each shift begins with surprises.
Questions about this role
Not automatically. Check people skills and give a trial with training and review before confirming.
Coach on clear expectations and fairness, give examples from records and observe. Do not move straight to punishment.
The ladder is similar, but foundries add heat, moulds and pouring, while assembly adds line balance and parts supply. Adapt the safety and process content.
