Managing spare parts is an essential task for any company that manages different sectors. The spare parts category has a higher level of uncertainty in demand compared to other products. Within the lifetime of machinery that is designed to last for more than a decade, there are chances of a part malfunctioning or getting worn out.
Different parts are categorized internally on the basis of their demand. For example, a part that has a long period of time between two repairs is set to one category, parts that need to be changed frequently are placed in another, etc. To sustain customer satisfaction, it is essential for OEMs to maintain their spare parts inventory cautiously.
What is Spare Parts Planning
In the manufacturing industry, OEMs have to pay extra attention to planning and prediction of the supply of spare parts. This coordination with the suppliers is crucial for handling a smooth management process. Only through the right execution can manufacturers ensure timely repairs and services.
Spare parts planning is far more than having parts available in the inventory. It can affect the performance of dealers, directly affect the downtime of equipment, and affect the performance and reliability of the company. It also helps in managing costs, as having too much inventory can lead to high costs. While falling short of inventory can result in unnecessarily costly delays.
Importance of Spare Parts Planning
Operational efficiency of OEMs is closely related to spare parts planning and management. Without a proper plan or prediction data in place, OEMs can end up with surplus or scarcity of parts. Either way, such management can be costly.
A shortage of parts can lead to delays in repair, extend downtime for the equipment, and frustrate the customer, damaging the reputation of the company. The need for spare parts inventory management is severe with products that have diverse spare parts. For example, a product like an automobile has about 30,000 spare parts, and managing such a vast inventory is a huge challenge.
Managing vast data of spare parts has been a huge challenge for OEMs. To keep up with the demands and manage the surplus pressure on inventory, robust spare parts inventory management software are actively being used by OEMs.
