During the testing phase of the model, planning, analysis and measurements has been performed in order to achieve suggestions that would lower the variation within the production at the case company.  The result of this thesis and the model is that with the use of the model developed in this thesis it is possible to achieve lower variations in the production. The thesis is aimed to be suitable to Swedish industrial companies. The authors provide a generic user-friendly model.  From the results recommendations to the case company has been developed. The thesis end with a discussion about topics not fully covered in the report.
