Direct and Indirect Costs and Customer Satisfaction
The studies showed that direct costs include component damage, additional transport costs and inventory management costs. Eliminating these direct costs alone could increase the profit margin of this business by 20%.
Using an Activity Based Costing analysis, a method for calculating costs and cost prices more accurately, Faes and the university expanded on the initial study into direct costs and identified the following factors:
- Logistics: Manufacturers maintain inventories worldwide so they can respond quickly on site. Some components are shipped around the world as many as ten times, moving from warehouse to warehouse.
- Diagnosis: The service engineer must provide a clear report, while customer service is responsible for proper intake and registration.
- Analysis: DOAs are investigated to determine their cause.
- Prevention: The analysis may show that stock purges are required or that the manufacturer needs to perform bin checks.
- Management: The manufacturer must implement improvements and take measures to prevent DOAs and maintain customer satisfaction.
The indirect costs of a DOA therefore include the costs incurred by all departments involved in diagnosing a DOA and the time they spend on it. These costs amount to 10% of profit.
Combined, the direct and indirect costs caused by DOAs account for 30% of the profit generated from the parts sold. Since it was not possible to quantify every component of a DOA in the study, this figure should be regarded as a minimum estimate.
Although these figures represent substantial costs for the companies included in the study, they identified customer satisfaction as the main reason for addressing DOAs. We believe this is justified. Our studies may have uncovered many hidden costs, but what would it cost if a customer began to question your reputation and decided to choose another supplier in the future?
