A manufacturer obtains raw materials from suppliers, processes them in a production center and distributes them to customers. Synchronous manufacturing and just-in-time manufacturing are two systems that allow manufacturers to reduce the time between the customer's placement of an order and receipt of the product. Even though the goals of these two systems are similar, differences exist between them. In synchronous manufacturing, production occurs in different production centers; some centers have constraints that limit the rate of production and some centers do not (Banton, 2020). Both types of centers must focus on using raw materials to produce goods that are nearly ready for shipment to customers, with the production schedule closely following the level of customer orders. The manufacturer saves money on the cost of transporting raw materials to production centers and by preventing the storage of raw materials near production centers that are not required for satisfying actual customer orders. The Just-in Time manufacturing model pursues a higher manufacturing velocity by phasing out any activity that does not increase value for a customer. The manufacturer wants to reduce the time between obtaining materials and finishing products, and may focus on problems such as overproduction, product defects and waste during transit of raw materials (Bianca 2016). The main difference between the two systems is in manufacturing velocity. Just-in-time production focuses on sourcing raw materials just in time for factory use according to a production schedule; it helps manufacturers be able to store low quantities of raw materials. Synchronous manufacturing ensures that a manufacturer processes raw materials into finished products in the order that customers place orders, or first-in/first-out. Like JIT, MRP aims to eliminate excess inventory, but unlike JIT it takes into consideration uneven demand and seasonality. While both JIT and MRP have their advantages and disadvantages, many companies experience the best outcome when using both solutions in tandem, allowing your parts department to enjoy the best of both worlds by balancing the risks of overages and shortages (Nordmeyer, 2017). Scheduled flexibility for JIT is level production for a minimum of 30 days, MRP is frozen for 30 days but variable in work centers, and for Synchronized Manufacturing, the process can be changed daily as needed.
