Managing your Materials Reserve requires matching the materials you have with the time needed to restock those materials. You can work through each material using the worksheet below.
A materials reserve is best used for purchased items like raw materials. Work in Process (WIP) and finished goods (FG) should be managed using a bin system to keep a steady flow that coordinates with your batch sizes. The materials reserve allows for a larger and less frequent purchase, a bin system is better for items made in house that can be replenished more regularly.
