Cloud Computing offers organisations a range of benefits, both economic and technological. However the decision to deploy a ap- plication or service to the cloud is a not a trivial one. Organisations need to be fully aware of not only the business requirements for a given application or service, but also the technological requirements and or constraints of the cloud. Model-based process assessment and improvement has been shown to support organizational change in different domains of application, but there are few reports of application in cloud computing. As a first step in defining suitable models to support process management, the impact of working with cloud resources on existing standard processes has been examined using the techniques of behavior engineering. A path for future work is proposed.
