Introduction The practical part of the thesis describes the production program production system and the organization of the production process in a selected section of the company. The next section is an analysis of workplace policy and pre-assembly lines. Followed by an analysis of work and identifying current shortcomings. The next section are designed to improve a specific solution of identified problems. The last part of the thesis deals with the evaluation of implemented improvements and their benefits.

The main aim of the thesis is to optimize the management of the production process with the focus on the material flows in the manufacturing company Jung in Brno. The thesis takes into consideration the analysis of the current state of the company. In addition, the thesis describes the production programs and processes with the focus on the material flow and material stocks. The work also aims to identify and minimize bottlenecks in the production process. Apart from the main directions along which the material goes, the process of supply, removal from storage and efficiency of working with material during production is analyzed. The findings of the thesis of the work are suggestions that would make the operational business management effective, reduce production costs and increase the dynamics of the transformation process of production.

This thesis is based on inspecting, presenting and defining Lean Warehousing. With applying this philosophy, it is possible to minimize the wastes and maximize productivity and affectability in the warehouses. Enrad is the company that locates in Borås and is the producer of industrial coolers and heaters. Attentive to the first interview with parts of company members that were very interested to reorganize and standardize their warehouse, exploring the problem that exists right now in the place of producing and stocking makes easier to refine and refit the organization. The main purpose of this thesis is analysing the current situation of company, identify the obstacles and suggest the theoretical finding in order to apply Lean Warehousing, in additional to have smoothing production within reducing the different kind of wastes. Applying Lean does not mean to use this philosophy just in a special place in the system, it means to implement this approach in all the processes and actions that execute behind and inside the company. Lean is the assessment of any process that consists wastes and costs. The procedures of progression would be done in the first step by data gathering through some qualitative data like interview and own observations. At the second step, detail analysing and mapping the actual condition, and at the third stage clarifying the most related techniques from Lean in order to eliminate or remove the reasons of wastes and their effects. obviously, the information will be presented to managing team and then to the other members. The main problems were recognized: Incorrectly design of spaces, warehouse managing and furthermore weak leadership that cannot satisfy the demands of warehouse and staffs.

The diploma thesis applies to Lean management and it´s application in administrative processes. The goal of diploma thesis is proposal to increase the value added activities and to reduce waste at the same time in the area of administration. The methods of Lean management as 7+1 waste, Kaizen, Lean office, Six Sigma and Lean Six Sigma are applied in administrative processes in Shared service centre. These methods are evaluated by performance and productivity of processes.

Most construction companies want to deliver the best possible results for their customers while spending the least possible resources. Nevertheless, the construction industry has traditionally been full of unnecessary inefficiency regarding workflows. One of the most successful methods to prevent inefficiency workflow is lean construction. Lean construction consists of various methods that aim to streamline workflow as optimally as possible. Purpose: The purpose of the degree project is to use specific lean methods and tools to identify different waste and be able to use them to reduce downtime of a studied construction project. Method: A case study has been carried out where the project Heby - care homes has been studied. To gather more information a survey study has been done. To gather even further information about the project an interview was conducted with a person who has a leading role. Results: The result shows a analysis of the survey and the interviewe answers. It also includs working methods, transparency and waste minimization. Furthermore it includs solutions like identify problems, create order and structure, standardize and work on improvements. Conclusions: The conclusion that can be drawn is that standardizations in the form of checklists and guides need to be in each project. More openness and to review your chosen forms of agreement. To have a more dynamic working group that strives to achieve common goals and continuous improvements. These are the most important aspects of making a project effective.

Denna studie har undersökt och identifierat vilka utmaningar och slöserier som en däckbytesprocess står inför. Förvaltningen som författarna valt att pröva teorier på är Servicekontoret i Borås Stad. Produktionsprocessen i fråga är: Däckbytesprocessen.Syftet med studien var att undersöka hur det går att flödeseffektivisera en däckbytesprocess. Teorier prövades på Servicekontoret för att se vilka störningar som fanns och vad som kan göras för att minimera effekterna av dessa. Studien har även analyserat vilka utmaningar en däckbytesprocess behöver hantera och vad som kan göras för att bearbeta dessa utmaningar. Metoder som använts för att samla in data är kvalitativa- och semistrukturerade intervjuer, litteraturstudier samt egna observationer utifrån genomförda studiebesök. Värdeflödesanalys visar både nuläge och ett önskat framtidsläge. Resultat av studien visualiserar ett nuläge med en värdeflödeskarta. Analysen visar att den värdeskapande tiden i processen endast är 7 %. Processen har ett stort buffertlager inne i produktionslokalen för att minska effekterna av störningar. Störningar för processen är exempelvis att kunden inte kommer på bokad tid eller att utrustningen inte fungerar vilket innebär att processen stannar upp. Med ett förebyggande underhåll (TPM) av maskiner och utrustning i processen kan buffertlagret sänkas. En minskning av buffertlagringen kommer att bidra till ett bättre flöde in till däckverkstaden. Utrymme på golvet skulle frigöras då det inte skulle ligga så många däck i bufferten. Ergonomin kan bli mycket bättre om enheterna hanteras på höj- och sänkbara vagnar. Beslutet i val av däcksort dubbade eller odubbade kan omprövas och utvärderas eftersom dubbade däck bidrar till utsläpp av hälsofarliga partiklar. Slutligen kan verkstaden och förvaltningen dra nytta av ett aktivt och strukturerat förbättringsarbete med verktyg såsom 5S. Med föreslagna åtgärder kan den värdeskapande tiden i processen ökas från 7 % till 15 %. / This study has examined and identified the challenges and waste that a tire change process faces. The administration that the authors have chosen to test theories on is the Service Office in the City of Borås. The production process in question is: the tire handling process. The purpose of the study was to investigate how it is possible to streamline a production process. Theories were tested at the Service Office to see what disturbances existed and what could be done to minimize the effects of these. The study has also analyzed what challenges a production process needs to handle and what can be done to process these challenges. Methods used to collect data are qualitative and semi-structured interviews, literature studies and own observations based on completed study visits. Value flow analysis shows both the current situation and a desired future situation. Results of the study visualize a current situation with a value flow map. The analysis shows that the value-creating time in the process is only 7%. The process has a large buffer layer inside the production premises to reduce the effects of disturbances. Disruptions to the process are, for example, that the customer does not arrive on time or that the equipment does not work, which means that the process stops. With Total Productive Maintenance (TPM) of machines and equipment in the process, the buffer stock can be reduced. A reduction in buffer storage will contribute to a better flow into the tire workshop. Space on the floor would be freed up as there would not be as many decks in the buffer. Ergonomics can be much better if the units are handled on height-adjustable trolleys. The decision in the choice of tire type studded or unstudded can be reconsidered and evaluated because studded tires contribute to emissions of hazardous particles. Finally, the workshop and the administration can benefit from active and structured improvement work with tools such as 5S. With proposed measures, the value-creating time in the process can be increased from 7% to 15%.

This case study focuses its purpose on the use of Lean tools for identification and minimization of waste on small dental clinics. During the projects course we will examine how Lean tools can be used to identify different types of waste dynamics. Then which wastes that are identified and how these can be minimized. To answer these issues, we have studied a small dental clinic in Uppsala, Sweden that has yet to implement any type of Lean philosophy nor tools. What we discovered in the collected empirical data was that many types of wastes occur in between different working activities of the patient treatment process. To identify and help understand how to minimize these wastes we contacted a dental clinic that had already implemented the Lean philosophy. We discovered that the Lean tools 5S, Kaizen, visual management and value stream mapping would fit in and had their own specific area of use in the project. This was done to more precisely be able to answer the project purpose. In conclusion the Lean tools were very effective in identifying waste dynamics in the working space of a small dental clinic. Many of the wastes that affected the time to treat a patient were not previously noticed by the staff. The suggestions on how to minimize the wastes were used but not measured to its fullest extent. Instead, it shows how a small dental business can choose to implement the philosophy and tools if needed.

A continuous improvement project (CIP) is a structured improvement project using a team of people "typically representing different departments or units in the organization" working to improve a process or work area over a relatively short period of time, such as a few days or up to several months. A CIP may use different improvement methodologies and tools, and may thus be defined according to the improvement approach. For instance, an organization adopting Lean as an improvement approach is likely to have CIPs implementing Lean tools, such as 5S or value stream mapping. These projects may be referred to as Lean projects in general, although they may also represent accelerated improvement projects such as Kaizen events, Kaizen blitz, or rapid improvement projects. Alternatively, an organization utilizing Six Sigma as an improvement approach may have Six Sigma projects that use the Define-Measure-Analyze-Improve-Control (DMAIC) process and statistical tools. Some organizations adopt an integrated improvement approach, such as Lean Six Sigma, and therefore may have CIPs with an even broader set of tools from which to choose. Lastly, many organizations may have an improvement approach not characterized by any single set of improvement processes and tools, and thus, may be thought of generally as process improvement, or quality improvement, projects using a traditional methodology as plan-do-study/check-act (PDSA or PDCA). In this dissertation, all of these types of improvement projects are referred as CIPs. Since the 1980s, hospitals have been using CIPs to address some of the problems in hospitals, such as quality in healthcare delivery, internal process efficiency, communication and coordination, and the cost of services. Some hospitals have achieved significant improvements, such as reducing the turnaround time for clinical laboratory results by 60 percent and reducing instrumentation decontaminations and sterilization cycle time by 70 percent. However, as with many other companies, hospitals often experience difficulty achieving their desired level of improvements with CIPs. Therefore, the purpose of this dissertation is to identify the critical success factors (CSFs) related to CIP success. In order to achieve this goal, five objectives were achieved: creating a methodology to assess the maturity or evolution of a research field (manuscript #1), identifying a comprehensive list of CSFs for CIPs (manuscript #2), assessing the maturity of the published literature on CIPs in hospitals (manuscript #3), identifying the most important factors related to CIPs in hospitals (manuscript #4) , and conducting an empirical investigation to define the CSFs for CIPs in hospital settings (manuscript #5 and #6). This investigation was conducted in three phases: research framing, variable reduction, and model development and testing. During these phases, the researcher used the following methodologies and data collection tools: systematic literature review, maturity framework (developed as part of this dissertation), expert study, retrospective survey questionnaire, exploratory factor analysis, partial-least squares structural equation modeling, and regression modeling. A maturity framework with nine dimensions was created (manuscript #1) and applied in order to identify a list of 53 factors related to CIP in general, involving any organization (manuscript #2). Additionally, the maturity framework was used to assess the literature available on CIPs in hospitals, considering only the authorship characteristic dimension (manuscript #3). Considering the frequency of new authors per year, the relative new integration of research groups, and the limited set of predominant authors, the research field, or area, of CIPs in hospitals is one with opportunities for improving maturity. Using the systematic literature review from manuscript #3, the list of 53 factors, and the list of predominant authors, a review of the literature was conducted, along with an expert study to more fully characterize the importance of various factors (manuscript #4). A conclusion from this particular work was that it is not possible to reduce the list of 53 factors based on these results, thus, a field study using the complete comprehensive list of factors was determined to have stronger practical implications. A field study was conducted to identify factors most related to CIP perceived success (manuscript #5) and CIP goal achievement (manuscript #6). The final results and practical implications of this dissertation consist in the identification of the following CSFs for CIP success in hospitals: Goal Characteristics, Organizational Processes, Improvement Processes, and Team Operation. These CSFs include several specific factors that, to the researcher's knowledge, have not been previously studied in empirical investigations: goal development process, organizational policies and procedures, CIP progress reporting, and CIP technical documentation. Practitioners involved with CIPs, such as CIP leaders, facilitators, stakeholders/customers, and continuous improvement managers/leaders, can utilize these results to increase the likelihood of success by considering these factors in planning and conducting CIPs. / Ph.

La aplicación del Lean Management en las organizaciones conlleva la implicación de todo el personal en la mejora de todas las operaciones para disminuir, o eliminar, todo aquello que no aporte valor en las operaciones, mejorando la eficiencia de cada operación y, como consecuencia, del conjunto de la organización. Bien sea que las propuestas de mejora provengan de las aportaciones de los grupos de trabajo, a través de los Programas de Sugerencias, o de acciones Kaizen-blitz surge la necesidad de objetivar el proceso de toma de decisiones sobre su implantación. Conforme aumenta el tamaño de la organización también lo hace el volumen de proyectos de mejora y, con ello, la necesidad de gestionar eficazmente el sistema a través del cual fluyen, son analizadas y, en su caso, puestas en funcionamiento. En la práctica este sistema de sugerencias cubre tres funciones básicas. En primer término canaliza todas las propuestas de mejora desde las líneas de producción, y áreas de servicios, hasta la toma de decisión sobre su implantación. En segundo lugar, estos procesos permiten que parte del conocimiento tácito, acumulado en los miembros del grupo, pase a conocimiento explícito y pueda transmitirse y extenderse en la organización. Finalmente, constituye un importante factor para el enriquecimiento del trabajo del operario de línea que, por naturaleza, se caracteriza por su monotonía. Para mantener el empuje a través de toda la organización y a largo plazo el principal problema radica en mantener activa la participación del personal en el programa. Para soslayarlo todas las sugerencias deben ser evaluadas mediante criterios objetivos, sin que se generen dudas sobre su aplicación, y todo ello debe ser realizado en el mínimo plazo posible y manteniendo la comunicación eficaz con los equipos cuyas propuestas son evaluadas. Si estos elementos no son percibidos positivamente por el personal se pierde parte de la necesaria participación, lo que afecta directamente a la ....... / Barberá Ribera, MT. (2012).
