Hur minskas kvalitetsbristkostnader

Focusing on reduced quality deficiency costs (QDC) is one way of managing a quality project. Theory treats this in a simplified way. The aim of this study is to explain three ways to reduce QDC. The empirical part of the study is an extensive case study conducted in a printing company. Embedded units of analysis are two departments. Quantitative and qualitative data was collected during 2,5 years, mostly by participating observation. QDC showed a short-term variation.Activities of conformance, what is actually done to reduce QDC, showed no relationships with reduced QDC. Studied activities were appraisal routines, education and appraisal equipment. Handling of a problem solving process, how work is conducted, showed a clear relationship with reduced QDC. A complete PDCA-cycle leads to reduced QDC. Exogenic factors, factors not directly related to quality management, were found to affect the short-term variation. Heavy workload, few orders and continuous time reduced QDC.
