The project degree is written within the department of Industrial Engineering & Management at Uppsala University. The object with this study is to improve the current capabilities of the Internal Collection process at the service credit company Hoist Finance with the improvement methodology Lean Six Sigma and associated DMAIC cycle. In order to find out how the methodology should be adapted a case study and a literature study was carried out. The literature study was about previous research in the area of processes, Lean Six Sigma and the company Hoist Finance. The case study was performed over 4 months at Hoist Finance in the operational excellence team to understand how the methodology should be used on the company. The degree project shows great potential to apply the methodology to improve the process and if the recommendations on how the process should be performed is implemented, the process time can be reduced with 25 days and the costs with 23.34 euros per debt.

O Lean Six Sigma é a metodologia originada a partir da integração das metodologias Lean e Six Sigma. O Lean Six Sigma procura eliminar as perdas e reduzir os defeitos, agregando os benefícios de cada uma das duas metodologias que a dão origem. O objetivo deste trabalho é aplicar a metodologia Lean Six Sigma para melhoria de um processo produtivo. Neste trabalho é apresentada uma revisão bibliográfica sobre as metodologias Lean e Six Sigma, buscando a compreensão das origens do Lean Six Sigma, e uma revisão sobre a metodologia Lean Six Sigma. Baseado na revisão bibliográfica é apresentada uma metodologia para aplicação do Lean Six Sigma, que tem por estrutura o DMAIC (Define, Measure, Analyze, Improve and Control). Na sequência esta metodologia é aplicada para melhoria de um processo produtivo. Os resultados da aplicação do Lean Six Sigma foram: aumento do nível de sigma e redução dos defeitos do processo, demonstrando que as metodologias Lean e Seis Sigma podem ser integradas, e como ocorre essa integração. Os fatores de sucesso da aplicação da metodologia Lean Six Sigma também foram evidenciados. / Lean Six Sigma is a methodology originated from the integration of Lean and Six Sigma.

Abstract The Profitability of Lean Six Sigma: A Study of National Grain Producers Inc. describes the different actions taken by NGP to take advantage of Lean Six Sigma and increase the company’s profitability. These actions are reviewed as investments to aid in assessing how beneficial they have been. This approach helps to quickly determine if what has been done within NGP so far as part of Lean Six Sigma has been successful which helps in deciding whether or not to continue the use of the LSS system.

This report describes the major steps used in the Army’s LSS methodology, provides a brief overview of the Unaccompanied Personnel Housing and the Army Family Housing and briefly describes some of the initial steps intended to start improving the process. In the improvement phase, two detailed models (The EOQ Model and the Hadley and Whitin (Q,r) Model) used for inventory management are discussed. This report also provides a series of recommendations that include suggestions for baseline inventory levels, some ideas for future data collection, example improvements to some data input sheets as well as a few tasks for UPH and AFH managers to reduce cost and improve the overall efficiency of the system. / text

BAGA Water Technology är ett svenskt företag som är verksamt inom vattenhantering med fokus på konstruktion och tillverkning av reningsverk särskilt anpassade för att klara de nordiska förhållandena. De är en av marknadens ledande aktörer inom området vilket gör att en ständig utveckling krävs för att konkurrenskraften ska bibehållas. Företagets huvudkontor är beläget i Karlskrona medan produktion och lagerhållning till största delen är outsourcat till en underleverantör i Norge och en i Blekinge (UL.B). Outsourcingen till UL.B har visat sig inge problem då kvalitén av produkter inte är tillfredsställande samtidigt som den spridda lagerhållningen och produktionen gör logistiksystemet komplext och svårhanterligt. Arbetets syfte är således att göra en förstudie där BAGA erhåller data som kan användas för att ta beslut om en omorganisation av företagets outsourcade lager och produktion är en rimlig lösning på problemen samtidigt som implementerbara förändringsförslag tillhandahålls. Genom användning av Lean Six Sigmas modell för förbättringsarbete, DMAIC, samt förespråkade verktyg har först en nulägesanalys av processer och flöden kopplade till UL.B genomförts. Intervjuer och observationer både på BAGA och hos UL.B har verkat som grundläggande data. Utifrån den samlade informationen har en orsak-verkan analys gjorts med fokus på de båda problemområdena, där orsakerna sedan har prioriterats i en FMEA. Framtagning av tre förbättringsförslag har därefter gjorts, där det förslag som ansågs mest fördelaktigt är att BAGA bör investera i en utökad egen verksamhet genom tillbyggnad av en lagerbyggnad intill kontoret i Karlskrona. Detta möjliggör en förflyttning av lager och produktion från UL.B till BAGA. Beskrivningen av förändringsförslaget presenterar bland annat förändringar i processer och flöden men även förslag på en fysisk utformning där ett effektivitetstänk enligt Lean Six Sigma ständig genomsyrar arbetet. Slutligen presenteras en kostnadskalkyl som jämför nuläget med det föreslagna scenariot där det visar sig att förslaget ger en ekonomisk vinning. Utifrån de många positiva argument som har framkommit, bland annat att förslaget bidrar med minskade transporter och ett ökat inflytande över produktionen, anses det som ett strategiskt riktigt beslut att implementera förbättringsförslaget.

This diploma thesis deals with optimization of processes in operating theaters in the regional hospital. The largest consumption is in the operating theatre. It is a place where you meet all kinds of costs and where you find the biggest wasting of sources. The aim of the thesis is optimization of key processes taking place in operating theaters in healthcare institute. Optimization of these processes will enable more efficient, thus providing a management of healthcare institute tool for management. Process analysis will be performed using suitable models and methods of Lean Six Sigma.
