Abstract: Business process integration can be complex when it spans organisations. Existing grid technology aims to provide the capability to link processing between organisations, but does not presently provide manageable secure access to grid resources. Furthermore, current workflow tools connecting grid services lack security for collaborative workflows. The DAME (Distributed Aircraft Maintenance Environment) is used to illustrate the collaborative use of grid services in diagnostics workflows. This paper shows that a Virtual Organisation (VO) policy can be used to control access to a workflow executing collaborative services for different users from different organisations. The intention is to demonstrate mechanisms for securely sharing service instances using grid computers in a diagnostics environment.
