In today's logistics market, small and medium- sized logistics companies are exposed to increasing cooperation pressure to use rationalization potentials, win new groups of cus- tomers and assert themselves in the competition with big logistics companies yielding a distinct market power. In the past, numer- ous SME-size logistics companies have joined to form regional logistics associations in order to assess possible cooperation and develop cooperation potentials. In a parallel process, logistics cloud service providers develop new types of cooperation-support- ing logistics cloud services. This paper describes a method of how regional logistics associations can apply a cloud-based coopera- tion development process. The method was developed as part of a doctoral thesis and evaluated first hand by expert interviews in several logistics association in relation to the application in- volved. The results of the evaluation suggest that a suitable ap- proach was found by which regional logistics associations can tap the potentials of logistics cloud services for their member companies.
