IATF 16949:2016 clause Production scheduling

Production scheduling is the process of determining when products will be manufactured to maximize efficiency while limiting stock outs and unbalanced inputs and outputs. This process includes optimizing where, when, how, and what materials you will use to manufacture your products. A production schedule lists every single product that’ll be manufactured, including where and when they’ll be made. It includes every detail, from raw materials to logistics. It also incorporates various processes designed to make production run smoothly while helping managers spot potential issues — like bottlenecks — and stop them before they explode into something bigger. For this reason, it’s a flexible, changeable document that you’ll need to update and check regularly. As well as helping managers plan ahead, the production schedule works as a line of communication between production and sales teams. Sales inform the manufacturing team about the levels of demand. Manufacturers then tell sales when the product is ready. The production schedule is a versatile and important document for planning, forecasting, predicting, and meeting demand. It helps keep your operations working on time and under budget, which helps you keep your commitment to your customers. Let’s get into its main functions in a little more detail.
