korjaussuhde

Korjaussuhde, often translated as "repair ratio" or "correction ratio," refers to a metric used to evaluate the efficiency and effectiveness of a repair process or system. It quantifies the proportion of attempted repairs that are successfully completed without requiring further interventions or re-repairs. A high korjaussuhde indicates a robust and reliable repair system, where issues are resolved correctly the first time. Conversely, a low korjaussuhde suggests potential problems within the repair methodology, the skills of the repair personnel, the quality of spare parts, or the diagnostic procedures.

The calculation of korjaussuhde typically involves tracking the number of initial repairs against the number of subsequent repairs needed for the same issue. For example, if 100 items are repaired and only 5 require a second repair for the same fault, the korjaussuhde would be 95% (100 - 5) / 100. This metric is valuable in various sectors, including manufacturing, automotive repair, IT support, and maintenance operations, as it helps identify areas for improvement. Analyzing the reasons behind failed repairs can lead to process optimization, enhanced training, and better quality control, ultimately reducing costs and improving customer satisfaction.
