When a project work was performed at DHL Express in Borås in spring 2007 the time of the processes at the terminal was measured. DHL Express in Borås is working with two recruitment companies and the employees could therefore be divided into two groups; the permanent employees and the hired employees. There were a slight difference in performance between these two groups of employees and it was then questioned if DHL Express in Borås really was working in the best way with the recruitment companies. The theories that were used in this thesis work was; complexity theories by Murray Gell- Mann, Game theory by John Forbes Nash and Lean. These three theories were used at the same time to get the best outcome. The methods that were used was investigating the contracts between DHL Express and the recruitment companies, interviews with the employees at the tactical level that are in contact with the recruitment companies in their daily work with base from the contracts, conversations and discussions with employees, pictures was also taken to document parts of the terminal at DHL Express in Borås. The result of the thesis work was that a “best-way-package” how DHL Express in Borås should work with the recruitment companies was set up. This “best-way-package” could be applied on any terminal at DHL Express if wanted.
