Frequently asked questions

What does a plant manager do in a manufacturing company?

A plant manager runs daily plant operations. They review production, maintenance, quality and stores every day, approve the weekly schedule, lead root cause work on the biggest losses, enforce safety and SOPs on the floor and keep operating costs within budget. They report to the plant head or, where there is none, the head of manufacturing.

What qualifications are needed for a plant manager job?

Most plant managers are engineering graduates in mechanical, production, electrical or chemical engineering with 12 or more years of plant experience. Hands-on exposure to both production and maintenance is valued. Lean, Six Sigma or TPM training and familiarity with ISO or IATF quality systems strengthen an application.

How is a plant manager different from a production manager?

A production manager's job is making the product: shifts, output, manpower and process discipline in the production departments. A plant manager is responsible for the whole plant working together, including maintenance, quality, stores and dispatch, and settles the trade-offs between them. The production manager usually reports to the plant manager.
