Förbättringsarbete från order till leverans: End-2-end studie i en icke repetitiv MTO-baserad tillverkningsmiljö enligt VSM
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
In today’s competitive and partly turbulent and complex environment that enterprises operate in, the need for continous improvements, not only in the area of products and services but also in the area of processes, are very central. The importance of continuous improvements within all areas of the enterprise is greater today than ever, and the speed of change in the business environment has probably never been greater. Lean manufacturing, which first was implemented by Toyota has many valuable tools in its toolbox and one of those tools is VSM. VSM has been used as an unvaluable tool for identifying and implementing improvement possibilities in terms of removing waste, quality defects and reducing lead times with great success within repetitive non MTO-based manufacturing environments. ABB Metallurgy is a leading supplier of system solutions for among others stirring metallurgic melt. Furthermore ABB Metallurgy operates in a non-repetitive MTO based manufacturing environment and ABB Metallurgy think that there is improvement potential in the value stream from order to delivery. In order to detect the improvement potential and come up with improvement and implementation suggestions, VSM has been used. The purpose of this thesis was to investigate the applicability of VSM in a non-repetitive MTO based manufacturing environment in order to detect improvement possibilities with the target of minimising costs of poor quality from order to delivery. The study further aims to: (1) Investigate and identify advantages and disadvantaged with VSM as a tool for improvement of the value stream in a non repetitive MTO based manufactiruing environment in comparison with what VSM traditionally is developed for that is a repetitive environment. (2) Give recomendations about how practitioners can use VSM in a non-repetitive manufacturing environment to identify and work with improvements i the value stream. The thesis has been conducted using qualitative research and deduction as research approach. The research strategy in this thesis consists of a case study at ABB Metallurgy in Västerås, Sweden. The case study has been carried out between March and Juli 2011. Interview and observation has been used as data collection methods and what was observed during the study is documented during observation and interviews along the value stream from order to delivery. The results from the study show that it is possible to apply VSM in a non-repetitive MTO based environment in order to identify improvement possibilities, but the methodology needs to be adapted. Five improvement suggestions have been worked out with VSM; method for structured problem solving and RCA, method for feedback of experiences, improved document management, Kaizen visual management and method for measurement of customer satisfaction. The study shows that the statistical parts of the methodology such as cycle times, changeover times etc. becomes less relevant since both the manufacturing flow and tasks vary very much between orders. This makes it less relevant to gather data about cycle, changeover, wait times etc.
