The diploma thesis is focused on optimization of working processes in Witzenmann Opava by using Value Stream Map. The aim of the thesis is on a basis current status of value stram propose to suitable actions and draw them into new value stream map. The thesis is devided into three parts – theoretical, analytical and proposal part. In the first part of the thesis are compiled theoretical knowledge about lean management sphere, tools for elimination of wastings and theory about mapping value stream by using VSM. Analytical part is deal with characterictic of company Witzenmann Opava, its internal and external factors of developments and implementation of lean production. In this part there is also characteristic of choosed product. Proposal part is deal with value stream analysis of choosed product and specific actions to reduce wasting and getting production more effective with the help of lean production methods.

Bakgrund och problem: Trycket har ökat på Folktandvården under de senare åren på grund av en befolkningstillväxt vilket resulterar i en ökad arbetsbelastning för personalen och vårdköerna. Samtidigt rapporterar nästintill samtliga regioner en brist på tandläkare. För att hantera detta problem har flera regioner infört ett förbättringsarbete enligt Lean för att tiden ska användas bättre och att kunna utnyttja begränsade resurser på bästa sätt. Denna satsning har från många upplevts positivt då man kunnat se minskning i både väntetider och vårdtider vilket inneburit att bristen av tandläkare inte varit ett lika stort problem. Användandet av Lean-verktyg och Lean som styrmodell har vidare uppmärksammats med en viss motsättning som menar att Lean inte ska tillämpas i en miljö där patienter är i centrum. Traditionellt sett har det varit motsatta åsikter kring ämnet där ena parten anser att främjande av storskalig förbättring av industrityp behövs för att få vård in i modern tid. Den andra parten hävdar att människor inte ska hanteras som inom produktion och att en förenklad adoption bara förvärrar de extrema svårigheterna att leverera enhetlig, högkvalitativ vård med få resurser till befolkningar vars förväntningar fortsätter att öka. Men vid branscher såsom tandvård där personalen utgör både service och “produktion”, bör det vara av största vikt att se över vad som går att påverka för att förbättra deras arbetsmiljö så att de kan utföra bästa möjliga arbete med begränsad personal. Frågan som vidare uppstår är, hur påverkar egentligen användandet av Lean-verktyg arbetsmiljön och vidare arbetstillfredsställelsen hos personalen i folktandvården? Är ett skifte till ett förbättringsarbete enligt Lean en hållbar lösning för den tandläkarbrist som uppstått i landet?    Mycket av den forskning som utfört kring relationen mellan användandet av Lean-verktyg och personalens arbetstillfredsställelse har utförts i sjukhusmiljö. Vi resonerar att delar av denna forskning kan vara applicerbart inom tandvården då de bedriver en liknande verksamhet med patienter i fokus, men då forskning visat på att det finns skillnader i resultat av implementeringen även avdelningar sinsemellan är det av behov att studera tandvården närmre. Huruvida användandet av Lean och dess olika styrverktyg påverkar arbetstillfredsställelsen är därför av relevans att studera för att kunna komplettera den redan existerande forskning som finns inom hälso- och sjukvård.   Syfte: Syftet med denna studie är att redogöra för vilken påverkan användandet av Lean-verktyg har på personalens arbetstillfredsställelse på Folktandvården.   Metod: Denna studie har utförts genom en kvantitativ forskningsmetod med en deduktiv forskningsansats. Data har samlats in genom enkätundersökning från Folktandvården i 4 st regioner med frågor angående deras arbetstillfredsställelse samt arbetssätt.   Resultat: Studiens resultat tyder på att Lean-verktyget Value Stream Mapping har en positiv inverkan på personalens arbetstillfredsställelse. De andra Lean-verktygen som testades (Visuell styrning, standardiserat arbetssätt, 5S) hade ingen inverkan på personalens arbetstillfredsställelse. Vid test av en sammanslagning av samtliga verktyg så sågs en positiv inverkan på arbetstillfredsställelsen. / Background and problem: The pressure has increased in Folktandvården in recent years due to population growth as a result and an increased working life for staff and the care queues. At the same time, almost all regions report a shortage of dentists. In order to deal with this problem, several regions have introduced improvement work according to Lean in order to use time in a more productive way and to be able to make the best use of limited resources. This initiative has by many been seen as positive seen there has been a reduction in both waiting times and care times, which made the lack of dentists not as big of a problem as before. The use of Lean tools and Lean as a control model has also been noted with some contradictions which mean that Lean should not be applied in an environment where patients are at the center. Traditionally, there have been opposing views on the subject where one party considers promoting large-scale improvement of industrial type is important to move healthcare into modern times. The other party claims that people should not be treated as in production and that simplified adoption only exacerbates the extreme difficulties of delivering uniform, high quality care with few resources to populations whose expectations continue to increase. In industries use dental care where staff are both service and "production", it should be of utmost importance to look at what can be done to their work environment so that they can perform at their best with limited personal. The question that arises is, how does the use of Lean tools really affect the working environment and, furthermore, the job satisfaction of the staff in the dental care? Is shifting to an improvement work according to Lean and sustainable solution for the dentist deficiency that has arisen in the country?   Much of the research conducted on the relationship between the use of Lean tools and staff job satisfaction has been conducted in a hospital setting. We reason that parts of this research may be applicable in dentistry as they conduct a similar activity with patients in focus, but as research has shown that there are differences in the results of the implementation, also departments among themselves, it is necessary to study dentistry more closely. Therefore, whether the use of Lean and its various control tools influences job satisfaction is of relevance to study in order to supplement the already existing research that exists in health care.   Purpose: The purpose of this study is to report on the impact of the use of Lean tools on staff job satisfaction at Folktandvården.   Method: This study was done through a quantitative research method with a deductive research approach. Data has been collected through a survey by Folktandvården in 4 regions with questions regarding their job satisfaction and working methods.   Results: The study's results indicate that the Lean tool Value Stream Mapping has a positive impact on staff job satisfaction. The other Lean tools tested (Visual Control, Standardized working method, 5S) had no effect on staff job satisfaction. When testing a combination of all the tools, a positive impact on job satisfaction was seen.

Efficient use of resources and utility is the key to reduce the price of the commodities produced in any industry. This in turn would lead to reduced price of the commodity which is the key to success. Sustainability involves integration of all the three dimensions: environmental, economic and social. Sustainable manufacturing involves the use of sustainable processes and systems to produce better sustainable products. These products will be more attractive, and the industry will know more about the climate impact from their production.   Manufacturing companies use a considerable amount of energy in their production processes. One important area to understand the sustainability level at these types of industries is to study this energy use. The present work studies energy use in a large-scale tool manufacturing company in Sweden. Value Stream Mapping method is implemented for the purpose of mapping the energy use in the different operations. To complement this, an energy audit has been conducted, which is a method that include a study and analysis of a facility, indicating possible areas of improvements by reducing energy use and saving energy costs. This presents an opportunity for the company to implement energy efficiency measures, thus generating positive impacts through budget savings. Less energy use is also good for the environment resulting in less greenhouse gas emissions level. This also helps in long-term strategic planning and initiatives to assess the required needs and stabilize energy use for the long run. Social sustainability completes the triad along with environmental and economic sustainability. In this study, the latter is reflected with the company’s relationship with its working professionals, communities and society.

CGI är ett av världen största IT-tjänsteföretag med säte i Kanada. I Sverige erbjuder CGI flera tjänster där Business Process Services (BPS) är en av dem. Inom BPS finns grupperingen Data Documenting Services (DDS). DDS:s uppgift är att förmedla meddelanden till och mellan såväl människor som företag, via olika kanaler. Meddelanden som förmedlas i form av fysiska utskrifter, exempelvis administrativ post, hanteras inom tjänsten Printing Services. Administrativ post är till exempel kontrolluppgifter från skatteverket och försäkringsbrev. På Printing Services’ produktionsanläggning i Slagsta Strand söder om Stockholm printas, efterbehandlas och kuverteras drygt 440 miljoner sidor årligen, vilka genererar 150 miljoner försändelser per år. Ledningsgruppen på Printing Services anser att uttaget per investerad timme är för lågt, varför syftet med detta arbete är att utvärdera eventuella problem och identifiera potentiella förbättringar inom produktionen. Arbetets mål har varit att genomföra en kartläggning av verksamheten, utvärdera Printing Services mätmetoder samt identifiera förbättringsförslag inom varje delprocess och prioritera dessa. Resultatet är baserat på praktik, semistrukturerade intervjuer och visuella studier av delprocesserna.

The factors that generate this scenario are related to the incorrect distribution of work areas, the absence of standardization of the production process and unorganized workstations in the production line. The application of 5S’s tool, Value Stream Mapping (VSM) and a proposal for plant design are presented to solve the problem. After the application of the design solution, it was identified that 1 h and 23 min can be saved in transfer times, which can be invested in the manufacture of more products, improving the use of the plant’s capacity.

For these purposes, tools such as process maps, flowcharts, indicators, system layout planning tools, and 5S implementation are used, supported by training sessions for process participants. As a result, customer complaints were reduced by 0.13% per month, and the number of work orders handled by the site increased by 0.38% per month. Moreover, a 0.32% increase in man/hour productivity was reported, leading to a 44.32% decrease in Duster vehicle delivery times.

Currently, there is a monthly breach with its vehicle delivery policy. This policy refers to said company, it refers to a minimum of 92% of units towards the points of sale. However, in the last quarter of 2017 and the semester of 2018, it has only been met from 82% to 90%. These are 5% -10% that have not come to meet in each month, but also directly to the profitability of the company. On the one hand, storage costs are increased by each car that does not arrive or dissatisfaction is generated by the customer, this is the problem of 3 main causes, which is the installation time of radios, installation of alarms and more vehicles that are not served in the damage assessment area. As a root cause, we have the first, since, on the one hand, a bottleneck is generated by the lack of car attention and, on the other hand, represents 20% of the monthly sales of the case study, For what needs to be done to reduce this bottleneck and increase the capacity of the vehicles in this area, the damage is detailed, two lines of evaluation are carried out. This type of triage, we ensure a standardized work, since there was a group of vehicles waiting with different types of damage in the same operating line. Also, the delivery of vehicles on time is improved to 95% and the times of the areas of installation of radios, installation of alarms and damage assessment are reduced by 42.85%, 51.42% and 50% respectively.

Företaget AB är ett tillverkande företag som i dagsläget är Nordens största aktör för utveckling av kontraktstillverkning. Produktionsenheten upplever att de har alltför långa led- och ställtider och har därför efterfrågat en studie om dess produktionsprocesser för att identifiera problem som gör att processerna är ineffektiva. Syftet med arbetet var att undersöka och identifiera problem där en värdeflödesanalys genomfördes på produktionslinjerna 1,2 och 4. Genom undersökningen beaktades principerna inom Lean Production för att företaget i framtida arbete ska förankra dessa i verksamheten. Vidare var delsyftet med arbetet även identifiera och undersöka produktionsenhetens arbetssätt. För att uppfylla syftet med arbetet har tre delstudier genomförts: en litteraturstudie, en fallstudie och intervjuer. Från fallstudien, litteraturstudien och intervjuerna drogs flertal slutsatser, där bland annat att värdeflödesanalys är en lämplig metod att använda för att upptäcka slöseri. Dessutom att en stor del av ledtiderna i resultatet indikerade på många icke värdeskapande aktiviteter. Resultaten av examensarbetet genererade flertal förbättringsmöjligheter i både produktionsprocesserna och arbetssätten. Dessutom flertal förslag på hur Företaget AB kan implementera dessa i framtida arbeten för att ständigt gå mot förbättringar. / Företaget AB is a manufacturing company that is currently the Nordic region's largest player in the development of contract manufacturing. The production unit aiming for the improvement regarding too long lead and set-up times and has therefore requested a study of its production processes to identify problems that makes the processes inefficient. The aim of the work was to investigate and identify problems by conducting a value stream mapping on production lines 1, 2 and 4. Through the investigation, the principles of Lean Production were considered so that the company in future work will anchor these in the business. Furthermore, the sub-purpose of the work was also to identify and examine the production unit's working methods. To fulfill the aim of the thesis work, three sub-studies have been conducted: a literature study, a case study, and interviews. From the sub-studies several conclusions were drawn, including that value stream mapping is a suitable method to use in order to eliminate waste. The sub-studies also showed that the main contribution to lead times was due to many non-value adding activities. The results of the thesis work generated several improvement opportunities in both the production processes and working methods. Also, several suggestions on how Företaget AB can implement these in future work to constantly move towards improvements.
