Icke-värdeskapande aktiviteter inom byggservice : En fallstudie av Snitek AB

Sammanfattning: Background: The literature on lean service and practical implementation of lean service is very thin, as the use of lean as a tool in service-oriented companies is not as well established as in the industrial and manufacturing sectors. This has created an interest in us to investigate how lean service and lean tools can be adapted to be used in the construction industry. Purpose: The purpose of this study is to identify non-value adding activities and problem areas to provide suggestions regarding leantools that can help to improve the carpentryproject process from beginning to end. Methodology: To answer the question of which non-value adding activities arise in carpentry-projects and which activities and areas in the carpentry processes that could be improved through leantools, have been studied as a case study in a medium-sized construction company. A total of four interviews were conducted, in an early stage a pilot interview with the group manager was conducted to form an idea of the current situation in the case company. Thereafter three semi-structured interviews were conducted with the company's board member, group manager and an employed carpenter. The Lean tools 5S and Muda sets the theme of the interviews and addresses issues related to waste, nonvalue adding activities and work routines. The material gathered from the interviews is set against the theoretical frame of reference and forms the basis for the analysis and discussion of this study. Results: The interviews revealed that mistakes, rework, unnecessary movements and waiting times are common. Usually in the form of incorrect drawings, poor conditions in workplaces or inadequate planning before carrying out the work in the delimited area of wall-projects. The case company recognizes that a development should take place in certain areas, but that inefficiency is not only due to them, but also to external circumstances. Contributions: Modifications to the original eight waste categories have been made to more accurately represent wastes that arise in service-oriented professions. Problems that arise in connection with non-value-creating activities are largely due to a lack of communication, unengaged employees, and inadequate planning. The results of this study validate previous research in the area of lean service and contributes with a unique perspective, as the construction industry is difficult to define as it can neither be defined as manufacturing, production oriented nor service oriented.
