Lean Production, simply called Lean, is one of the most powerful concepts recently employed by many manufacturers and service providers in order to improve the quality of their products, eliminate any non-value adding activities from operation and reducing the costs of production. Relatively, Lean Services concept is created based on Lean Manufacturing to include service sectors. Many wastes exist within production and potentially all the processes related to that. Seven different types of wastes were being redefined over time to better fit service operations. A significant number of techniques have been defined in the Lean concept; make it possible to execute required actions for achieving such an improvement. Looking closer from different perspectives to operation helps the analyst to find the hidden wastes in the processes. With the help of Lean concept finding bottlenecks and problems will be much easier as wastes are categorized into different forms, so the analyst knows exactly where to look for it. After analyzing the current state, the next effort for executer is to try to eliminate these wastes and optimize the processes by applying Lean and other supply chain techniques. A future state then will be created to solve the problems observed in the current operating state and most importantly this state will offer a much smoother production flow and less wastage in the operation. This thesis is involved with use of Lean and Supply Chain tools in one of the UPS local centers aiming to operate on Lean principles in the end. This will bring the company continues improvement on the processes which helps the company in many aspects.

I en globaliserad och högt konkurrensutsatt värld så behöver företag och organisationer ständigt arbeta för att bli bättre och mer effektiva. Ett av de mest erkända förbättringsprogrammen är Six sigma som med grund i data arbetar mot mindre variation och bättre resultat i processer. Hur fungerar detta i miljöer där personalfrågor och människan är i centrum? Hur kan HR funktionen i ett tillverkningsbolag använda sig av Six sigma metodik i arbetet mot en lägre personalomsättning? Hög personalomsättning är något som i många fall är problematiskt, då det hindrar en kontinuerlig utveckling i arbetet och kräver stora utbildningskostnader. Finns det sätt att förstå personalomsättning med nya digitaliserade data, och hur kan kvalitetsverktyg användas för att minska personalomsättningen? Studien undersöker ett urval av de mest använda Six sigma verktygen och hur dessa kan användas i arbete med hög personalomsättning bland nyanställd personal. Med en metod som utgår från DMAIC modellen så bedöms utvalda kvalitetsverktyg. Parallellt så redovisas orsaker och lärdomar kring personalomsättning inom industrin. Genom intervjuer och datainsamling med organisationens chefer så framkommer indikationer på vilka parametrar som driver personalomsättningen. Studiens resultat visar på att det fungerar väl att applicera Six sigma verktyg på HR problem, även om det finns vissa begränsningar i användandet av statistiska verktyg. Resultatet mynnar ut i en sammanställning av de mest effektiva verktygen för detta problemområde och ett förslag påmodell som chefer och rekryterare kan använda i förbättringsarbeten / In a global market with high competition the need for companies to improve and streamline their processes increase. One of the most well-known improvement programs is Six sigma, that has its background in data analyses to improve variance in a process. How does it work in an HR environment where most problems are human and behavior based? How can an HR department in a manufacturing company use common Six sigma methodology in its work towards lower employee turnover? High employee turnover is problematic for many companies, and it affects the continuity of the organization and result in costly education. Is there a way to understand employee turnover with new digital accessible data, and how can you use quality tools to improve the area? The study explores a choice of the most used six sigma tools and sees how these can be used in the work against high employee turnover specifically for new employees. The method is based on the DMAIC model and rate the chosen quality tools along with reflections to learn and understand what drives employee turnover in this industry. Through interviews and datacollection with the managers of the organizations some indicators appear that could show us the causes of the turnover. The result shows that six sigma tools are effective in problem solving even in HR related problems, even if it does show some restrictions compared to regular production problem types.The study delivers a list of the most effective tools and a model for recruiters and managers to use when working with future HR problems.
