SammanfattningExamensarbetet har utförts under 2012/2013 och är en avslutande del i vår utbildning inom industriell ekonomi.Vi har valt att fördjupa oss i Lean och se hur vi kan få in denna metod och ?tankar? i den administrativa delen av akademin. Lean används idag inom många olika sektorer och är en erkänd förbättringsmetod vars syfte är att skapa nya smarta och utvecklande sätt att utföra sina arbetsuppgifter på. Dessutom ska det vara gynnsamt för medarbetarna som arbetar i detta och verksamheten som helhet.På administrationsavdelningen på ingenjörshögskolan i Borås finns intresset av att se vilka möjligheter Lean kan medföra för en särskild process. Denna process önskar de få förtydligad och förhoppningen är att eliminera riskerna för fel och missförstånd.

Sammanfattning- ?Tids- och arbetseffektivitet i ett konsultföretag ? jämförelse mellan Lean och HighWay?Nivå: Magisteruppsats i hållbar verksamhetsutveckling och management, 15 HPInstitution: Akademin för ekonomi, samhälle och teknik, EST, VästeråsNyckelord: Tidseffektivitet, arbetseffektivitet och LeanFrågeställning: Hur skiljer sig effektiviteten i arbetet mellan de två systemen Lean och HighWay och skulle det vara en fördel för Hallvarson & Halvarson (H&H) att byta till Lean? Hur skiljer sig tids- och arbetseffektiviteten åt inom de två olika systemen?Syfte: Syftet med studien är att ta reda på om Lean, som från början var utvecklat för produktionssektorn, skulle kunna vara ett mer framgångsrikt system än HighWay för ett tjänsteföretag som konsultföretaget Hallvarsson & Halvarsson.Metod: Informationen har hämtats från vetenskaplig artiklar och litteratur samt internetsidor. Undersökningen bestod av två intervjuer, med system ägaren och VD på Hallvarsson & Halvarsson. Intervjuerna bestod av personliga möten.Slutsats: Förbättringsförslag för ökad effektivitet redovisas, där ett av förslagen är att HighWay skulle kunna införa en process- och kvalitetsövervakande roll med syfte att säkerställa ständigt och omedelbart förbättringsarbete för att uppnå perfektion likt Jidoka-principen..

The aim of this case study was to investigate the role of leadership and interpersonal relations among staff during implementation of lean at a University Hospital in Sweden. The 15 respondents were leaders and staff members from different wards and clinics, who had started working according to lean principles. One of the methods used was explorative, low structured interviews. Other methods used for gathering information about the case was attending lectures about lean healthcare at the hospital, part-taking in the lean game and reading articles about lean and the implementation in both daily press and on the intranet of the hospital. The results showed that an open and accessible leader that coaches his/her staff and supports their work, helps the staff to develop a lean identity.

During the middle of the 18th century the development of Toyota Production System, TPS, started in order to streamline the processes. TPS was based on the principles of assembly line production but unlike previous performers Toyota let the manufacturing be constantly affected by demand. At the end of the 18th century TPS was described by Womack and Jones in the book "The machine that changed the world - the story of lean producion" where TPS got the name lean. The principles behind lean is to maximize customer value and eliminate waste which means making products and services more valuable to the customer. 1Lean was for a long time a philosophy and an approach limited to industries and production based companies.

Lean is a production philosophy which is about increased resource use while meeting customer requirements. The foundation of lean comes from Toyota and their production philosophy The Toyota Way. Professor Jeffrey k. Liker has worked with Toyota's production philosophy and Lean for a long time and has created a 4 P model and 14 principles that characterize the Toyota production system (TPS), which many sources refer to.The aim of my work is to study the working procedure of asphalt projects from sales to the laid asphalt with a focus on planning and production management. The goal is to examine how the lean philosophy can be applied in planning and production to simplify the flow of asphalt projects based on Likers model and principles.

Part 1 of 2  ? Lean philosophy ? five steps to get the workplace in order?Part one deals with the theory of what Lean and 5S are.Lean is a long-term approach that involves a quest to become the best on the market by increasing employee engagement, eliminate waste and focus on the right things.5S is a method of order in a system. Businesses around the world are using these 5S which stands for sort, straighten, shine, standardize and sustain. Part 2 of 2 ? Lean philosophy ? five steps to get the workplace in order?Part 2 deals with the practical about 5S and a short summery about the company Wibax AB where the degree thesis took place.Wibax has a a project which involves using 5S in practice and create order in the in preparation lab and in the control room.By finding a solution to this mess reduces the time that was previously spent on searching equipment. Instead of search, the workers can do the real work..

Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.

Increased competition in the IT industry has sparked a need for developing faster innovation processes with more predictable output. One of the biggest issues when it comes to achieving a faster flow through the innovation process lies in managing its high degree of variation. Proposing a solution to this problem, Lean Software Development (LSD), was developed to provide a framework for how IT companies should organize its software development process to achieve increased speed and quality. This study examines to which extent LSD, as a set of values, principles, methods and tools, can be used to improve flow efficiency in the innovation process. A case study of a multinational IT company was made by conducting ten semi-structured interviews with current employees.

Today, the management concept of lean has stretched far from its origins in the Japanese automobile industry. When reaching the Swedish restaurant industry, the conditions for a successful implementation of lean change as a result of the high employee turnover and the significant amount of part-time employees characteristic for the industry. Combined with a high-end service profile, these workforce characteristics seem inconsistent with some of the basic principles of lean. By conducting a case study, this thesis aims to investigate the effects of a variable workforce on the enablers for a successful implementation of lean in a high-end service industry. Using a theoretical framework consisting of enablers for an implementation of lean in services, the study finds that the variable workforce inhibits an implementation of lean by complicating the effects of traditional training, as well as the possibility of understanding the lean concept at all levels of the organization.

Lundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of steel such as stainless steel. Lately, they have shown an interest in Lean production.On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions: Which wastes can be found with help from a value stream mapping (VSM)? In what way can these wastes be reduced and how can these reductions contribute to an improved production? VSM is the method used to find the non value-added wastes.

During the last decades the importance of IT has increased for businesses all over the world. It has transferred from only being used in administrative purposes to become more integrated to the core business. Due to the financial crisis in 2009 and increasing globalization, IT is facing the challenge of lower costs and increased efficiency. This requires IT-departments to embrace new strategies in order to fulfill these new tougher demands.Lean is a business development concept that aims to lower costs through more effective processes by removing all activities that does not create any value from the end customer?s perspective.

Swedish agricultural businesses are facing challenges in order to achieve long-term profitability. The opportunity to improve profitability and efficiency on farm level may be enhanced by management. One way to work with leadership is to use Lean. It is a management system that aims to improve competitiveness. Currently, there is a project where Lean is implemented into 100 agricultural firms.

The emergency medical care in Sweden has been under persistent debate, due to factors such as long waiting hours, inefficient patient flow, and understaffed departments. In an effort to meet the critique and with a willingness to improve the problems, an increasing amount of emergency clinics are adopting theories and models within Lean. Positive outcomes are evident, there has been some criticism directed towards Lean. Among these is the argument that in order for Lean to be successful it needs to be used within standardized and foreseeable processes, and that it therefore only is applicable to those kind of processes found within industrial production. This prompted the question of whether Lean was a suitable strategy within emergency medical care, considering the large variation of patients and non-foreseeable processes that in fact share little resemblance to that of industrial production.
