A lot of companies see Lean production as an opportunity to create a more efficient production system. This study is performed as a case study in a Swedish engineering company. The company is today troubled with long lead times and a flow of material that is hard to follow. This leads to difficulties whit the planning and it is hard to calculate how much an order will cost. A large amount of complicated orders in combination with lack of relevant monitoring makes it hard to get a grip of the factors that leads to the long lead times.
