In the domain of business-to-business (B2B) collaboration, companies are pursuing the objective of electronically linking their business processes for improving their supply chains. For creating such inter-organizational collaboration, intra- and inter-organizational knowledge workers (IKWs) function as assisting experts. However, IKWs must not constantly "reinvent the wheel" but should instead be supported by a repository that contains knowledge about how to design business processes. Thus, this paper proposes the support of IKWs by a pattern repository for the effective and efficient design of inter-organizational business processes. A pattern is conceptually formulated knowledge that is technology independent. By storing patterns in a uniform specification template of a meta model, it is possible to perform systematic reasoning. Having information readily available about the technology support of individual patterns, IKWs can quickly analyse with which intersection of pattern sets it is possible to link intra-organizational business processes.
