Den traditionella produktionsplaneringens död

Sammanfattning: This report focuses on the planning of production in the construction sector. The objective of the planning is to manage the building process as time and cost effectively possible. Nevertheless the traditional method used by the industry for doing this has been proven to produce waste in resources and time. The intention of this report is to introduce alternative improvements to that traditional method which would reduce the waste generated by it. These improvements are selected from a different planning method called Last Planner System. That method comes from Lean Construction, a philosophy which aims to make the construction sector more efficient. Through a collection of tools within the Last Planner System the actual worker who execute the task planned, gets involved in the planning. In the traditional planning method the worker is excluded from the planning process which is handled by the management of the project. The worker has a unique ability to highlight predicaments on site that will affect the progression of the project and its tasks. Last Planner System believes that the inclusion of this knowledge amongst other things are keys that will make the finished schedule better. The expertise which the worker contribute to the planning costs a certain amount of their time but is repaid by the transparency to the projects intended development, otherwise only wagly known to the worker. It also makes it possible for the worker to approve the schedules ability to be executed, and in that way promise it to be. Knowledge about the projects planned development will give the daily work on the construction site a clearer meaning to the completion of the whole project. Knowledge of the importance of the work should increase the motivation to complete that work in time - according to the plan. This work is based on a literature study of the concepts Lean Production, Lean Construction and Last Planner as well as a qualitative research of the construction company Rekab Entreprenad AB's planning model. The qualitative research was made up of interviews with people responsible for planning at Rekab AB. The fact that Rekab is good at managing their projects with the traditional method they use today complicates the implementation of the four improvements presented in this report. However, they’re enthusiastic about always getting better, which gives hope that the results of this report will be introduced when the company finds time for it.
