Effektivisering med hjälp av Lean : Hur kan principerna om Lean appliceras för att förbättra arbetsprocesserna i en organisation?

Sammanfattning: The aim of this study was to research which Lean principles that could be incorporated in a small company. Lean is a more and more common expression that has become popular among companies that strive to find new ways of improvement and creating ways to compete on the market.  Lean as whole can be viewed as methods to increase the effectiveness of ones working processes through handling waste and increasing customer value. The company that was chosen for this study was Lundqvist Trävaru AB, a small family company located in the city of Piteå in northern parts of Sweden. Their main product is to create wall blocks that can be assembled into garages, cottages and storage units. The study was constructed in physical visits to the company while conducting participatory interviews and observations. A theory study was also conducted to find information important to carry on studying and analyzing the subject. The collected data was compiled into value stream maps and spaghetti diagrams covering the work in the factory of the company, then a MUDA-analysis was made to locate different types of waste and suggestions of improvements to eliminate this waste. To quantify the study a capacity process index (Cp) and specific capacity index (Cpk) was calculated and compared to the numbers in theory. The results showed that there are good possibilities to implements Lean principles into the company. The Cp and Cpk -index that was calculated gave an unclear result, this probably as a result of it being a difficult process to demonstrate this type of calculation. The conclusion of the study is that it has given a result and that there are possibilities to conduct further studies on the subject.
