This thesis aims to investigate which elements of the design process in production that have key features for successful progress of production and how these are regulated in the developed production model, the NCC Project planning, NCC Construction Sweden AB. A study of NCC Project planning used in construction output in the department of Mälardalen has been carried out and proposals for implementation of the model has been proposed. The work is carried out through interviews and archival analysis of NCC's business system.  NCC Project planning is a production model based on LEAN Construction's governance model pull-planning and 5S principle. By means of the production model desired involvement in the work and control over the work process increase. In the current situation is not production model to the extent that the company wishes and therefore the reasons why mapped and solutions to the problem have been proposed.  One of the biggest reasons that the NCC Project planning is not used in practice is the lack of commitment from supervisors, managers and production managers. As a solution to the problem suggested mentors, field trips and custom training for production management model.
