The production plan is a high-level plan that defines the level of output to be produced for each product family or group in a given time period. It is based on the sales forecast, the aggregate production capacity, and the desired inventory levels. The production plan does not specify the quantities of each individual product to be produced, as this is done in the master production schedule. The production plan also does not include the sales forecast or the business plans for the company, as these are inputs to the production plan, not outputs12 References:
