The important role of using material requirements planning (MRP)
You have learned about the important role of using material requirements planning (MRP) to ensure that materials are available when a company needs them and to minimize unnecessary inventory taking up space and costing money. This exercise will provide you with an opportunity to develop an MRP for your small business that is rapidly growing.
Your company manufactures sanitizing products, and the recent pandemic has caused your business to triple overnight with no sign of slowing down. This growth has made you rethink the way in which you are running your business and fulfilling orders.
Review the article Not Just for Manufacturing, Material Requirements Planning (MRP) is Indispensable for Any Business for more information on the importance of an MRP.
Write a 3–5-page paper that covers the following topics:
What questions do you feel your team should ask in addition to the 3 key questions when planning for MRP?
Describe the steps and processes that you feel are necessary for your company’s MRP, and explain their importance.
Discuss the obstacles you might run into using your MRP and what you plan to do to resolve them.
Sample Solution
The three key questions of MRP are:
- What is needed?
- How much is needed?
- When is it needed by?
- What are the lead times for our suppliers?
- What are the risks of disruptions in our supply chain?
- How can we optimize our inventory levels to minimize costs while still meeting customer demand?
- How can we use MRP to improve our production planning and scheduling?
- How can we use MRP to track our inventory levels and forecast future demand?
- Gather data. The first step is to gather data on our products, our suppliers, and our customers. This data will include things like the bill of materials for each product, the lead times for our suppliers, and the historical demand for our products.
- Create a master production schedule. The master production schedule (MPS) is a plan that specifies what products we will produce, when we will produce them, and in what quantities. The MPS is based on our customer demand forecasts and our production capacity.
- Calculate the material requirements. Once we have a MPS, we can use MRP to calculate the material requirements for each product. This includes the quantities of raw materials, components, and subassemblies that we need to produce each product.
- Schedule the production. Once we know the material requirements, we can schedule the production of each product. This includes things like the work orders that need to be created, the machines that need to be used, and the labor that needs to be scheduled.
- Track inventory levels. It is important to track our inventory levels so that we can ensure that we have enough inventory to meet customer demand without overstocking. MRP can help us track our inventory levels and forecast future demand.
- Inaccurate data. If the data that we use to create our MRP is inaccurate, then our MRP will be inaccurate as well. This can lead to stockouts or overstocks.
- Unreliable suppliers. If our suppliers are not reliable, then we may not be able to get the materials that we need when we need them. This can lead to production delays or disruptions.
- Changes in demand. The demand for our products can change unexpectedly. If we do not have a flexible MRP system, then we may not be able to adapt to these changes.
