To become a production planner, you typically will need some form of higher education, on-the-job experience, certification, and familiarity with job-specific computer programs. Most employers will be open to hiring someone for a production planner position with little or no experience if a candidate has the appropriate education and understands production systems and processes.
Production planning helps you manage open time, ensuring it is well-utilized, while being careful not to create delays. Planning should maximize your operational capacity but not exceed it. It's also wise not to plan for full capacity and leave room for the unexpected priorities and changes that may arise.
