Abstract [en]

Throughout history companies have come to realize the importance of work revolving quality in order to remain competitive on the market. Process development is a natural part of quality management. There exists several different philosophies and tools to make use of in this work, examples are Lean Production and Six Sigma. The state of research of the programs are well studied, but the combination of Lean and Six Sigma's work methodology DMAIC has many unknowns. The objective with this study has been to integrate Lean with DMAIC. The study's purpose has been to investigate whether DMAIC is consistent with theories about Lean. The question this study tried to answer is how Lean-DMAIC can be used to minimize inconsistencies in flow of information in a global production company. The purpose of this paper has mainly been answered with the aid of the literature study. The question at issue has mainly been answered by the case study. The objective has been answered with a combination of the case- and literature study. The work procedure is based on DMAIC´s methodology, while Lean provided the tools for success in combination with the philosophy´s train of thought that permeate the work. The results of the study illuminated that Lean-DMAIC works in a simultaneous fashion in order to find inconsistencies in existing flows of information; with these results the study's question has been answered. By the end of the study it was possible to ascertain that a better question for this particular study would have been how Six Sigma is consistent with Lean, as DMAIC is a method, thus they cannot be directly compared. In this study, DMAIC provided the step-for-step method for how to model the work and in what manner the process was examined. Lean on the other hand provided the right tools and the train of thought in order to succeed. This culminated in that several improvement measures could be produced based on the study's results.

Abstract [sv]

Företag har under historiens gång kommit att förstå vikten av kvalitetsarbete för att vara konkurrenskraftiga på marknaden. Processutveckling är en naturlig del av kvalitetsarbete och det finns olika filosofier och verktyg tillgängliga för ändamålet, exempelvis Lean Production (Lean) och Sex Sigma. Forskningsläget av dessa program är välstuderade, men kunskapen om kombinationen av Lean och Sex Sigmas arbetsmetodologi Define-Measure-Analyze-Improve-Control (DMAIC) är lägre. Målet med undersökning är därför att integrera Lean med DMAIC och syftet är att utreda huruvida DMAIC är konsistent med teorier om Lean. Studiens frågeställning har varit hur Lean-DMAIC kan användas för att minimera avvikelser i informationsflöden i ett globalt produktionsföretag. Syftet uppnås med hjälp av en litteraturstudie, frågeställningen besvaras med hjälp av en fallstudie och målet med en kombination av studierna. Fallstudiens arbetssätt baseras på DMAIC som metodologi för arbetets struktur, medan Leans filosofi genomsyrar arbetet samtidigt som dess verktyg utnyttjas. Resultatet visade att Lean-DMAIC fungerar simultant, både teoretiskt och praktiskt, för att upptäcka avvikelser i informationsflöden. Därmed har undersökningens mål uppfyllts. Efter studien gick det att konstatera huruvida en bättre frågeställning hade varit hur Sex Sigma är konsistent med Lean, eftersom DMAIC är en metod framför filosofi. DMAIC gav steg-för-steg metoden för hur arbeten utformades och processen undersöktes, medan Lean gav verktyg och rätt tankesätt för att lyckas. Detta resulterade i förbättringsåtgärder åt företaget där fallstudien genomfördes.
