In manufacturing, priority planning is a production scheduling method that gives higher-priority items precedence over lower-priority things, ensures that the essential items are produced first, and helps prevent bottlenecks in the production process. One way to think of it is this: If you have a list of ten items, and item number one is a priority, then item number two would be the next priority, and so on. Priority planning allows manufacturers to plan for and produce the essential items to meet deadlines and meet their customers' needs.
