Planning and control, often known as production planning and control, are management functions that seek to determine: first, what market demands are stating and second, reconcile how a company can fill those demands through planning and monitoring.
Planning is required for day-to-day processes, like scheduling, dispatch inspection, quality assessment, inventory control, supply and equipment management. Control ensures that the execution of those items is done optimally, both in terms of cost savings and efficiency.
While planning sets out the goals, mission and steps for companies to meet market demands, controls are put into place so that companies can contend with changes when they inevitably occur. In other words, control ensures that companies can adapt and change their plans and processes swiftly. All in all, planning and control ensures that inventory is maintained, staff is scheduled properly, production matches demand, and the production line runs like a well oiled machine.
