    Abstract : Since the ending of the Cold War, the defence sector, particularly the areas of military logistics and defence acquisition, has been undergoing a comprehensive transformation. There are several factors that explain this transformation: changes in defence and security policies for nations and organisations; reductions in defence expenditure; participation in Peace Support Operations; Lessons Learned from these operations, especially in the area of logistics; revolutionary development in the area of Information and Communication Technology; emergence of novel Commercial Best Practises in the areas of business and business logistics; and changes in the legislation regarding the conduct of public procurement in Europe.
