basic information
Regarding the storage cost rate (Carrying Cost %) The storage cost rate (Carrying Cost %) is the percentage that represents the storage cost calculated as unit price multiplied by the storage cost rate. Specifically, it indicates what percentage of the unit price corresponds to the storage cost per item over one year. So, what are storage costs? 1. Equipment costs and utility expenses required for storage (including construction costs of company warehouses or depreciation costs of warehouses) 2. Insurance premiums 3. Transportation costs 4. Inventory costs (including related labor costs) 5. Loss processing due to obsolescence, design changes leading to unused items, shrinkage, theft, and discrepancies with ledgers 6. Cost of capital (inventory requires investment of funds, which incurs costs for financing, including borrowing interest) There are calculation methods, but in reality, I think it is difficult to compute. Basically, when inventory becomes surplus, there are often cases where it is written off or disposed of after inventory checks. It is considered that the weight of waste costs as "the price of hoarding unnecessary items" is significant, and it seems reasonable to assume a storage cost rate of 30%.

Company information
Investment in DX is unnecessary. Is it linked to returns (profits)? While DX was invested in for efficiency improvement, did it actually yield returns? Was the goal to achieve visibility through DX? Visibility can be achieved without DX. By utilizing TOC (Theory of Constraints) for targeted improvements that do not require high investments, we can dramatically enhance corporate profits. The three important questions when discussing TOC are: 1. Did sales increase? 2. Did operational costs decrease? 3. Did inventory decrease? We provide consulting to identify bottlenecks that hinder profit improvement and follow the five steps of TOC to increase sales while dramatically enhancing profitability. We also hold TOC training workshops. Please feel free to contact us. I have obtained the international qualification (Goldratt Master Executive Certificate for TOC Holistic Management). The complete Japanese animated version of "The Goal," a favorite book among top global executives, has been created and edited by Goldratt Japan. For more details, please contact us.
