Kvalitetsutmaningar i produktionsberedning : En grundorsaksanalys hos Siemens Energy AB

Sammanfattning: A successful company is characterized by shared values, a clear vision, continuous improvements and everyone’s commitment. By consistently striving to achieve and exceed needs and expectations, quality becomes a cornerstone of long term success. The study, which was conducted at Siemens Energy in Trollhättan, explored quality challenges in production preparation. The theoretical framework explores the foundation of quality. Furthermore, quality deficiency costs and tools for quality management are explored, all of which are considered essential for understanding the study and field. The initiative for the subject was taken by Siemens Energy AB who has perceived flaws in their production preparation. The purpose of the study is to minimize internal quality deficiencies that can be derived to production preparation. The goal of the study is to present a root cause analysis of the current situation. The study includes data collection, description of the current situation, and a root cause analysis with associated proposals of improvement. The methodology used is proactive quality development by Bergman and Klefsjö, which is based on TQM – Total quality management. Data collection was done from three different source types: deviation reports, measurement of disruption in production and interviews. The interviews consisted of three in-depth interviews with production manufacturing engineers and ten shorter interviews with operators. The identified quality challenges in the current situation includes, but are not limited to, errors in operation text and insufficient instructions. The root cause analysis focused on insufficient instruction and revealed several aspects of why instructions have poor quality. The two most significant reasons identified were: Instructions are difficult to understand and can be interpreted in different ways by different people and Instructions are not considered to be of great importance from a quality point of view. Considering these reasons, suggestions for improvement have been drawn up. The suggestions for improvement are summarised as follows:  Integrate knowledge and understanding of the importance of quality deficiencies in training and education in the organisation  Implement a systematic way of working that enables more efficient communication between operators, production technicians  Implement the critical moment add-on sheet in the existing instruction template
