This report will reveal the results of bachelor thesis project at Innovatum AB in Trollhättan, Sweden. The project is a continuation on earlier projects done in the same field of study. It all started when scientists at Innovatum AB conducted a research about the theory of easily finding bottlenecks in a manufacturing production. This would be done without using mathematical calculations or time measurements but simply by observing and walking along the production flow.

The purpose of the study was to evaluate this bottleneck theory by using it in practice and analysing the results.

The result and conclusion of the study shows that the method is useful for simple bottleneck detection. One prerequisite is that the inventory levels are clearly visible. The method works moreover better when the inventories are not used as a repositories for a longer period of time.
