With the development of e-business, the collaboration between enterprises is increasingly strengthened, which, at the same time, challenges coordination technologies in distributed enterprise transactions. Workflow management has as its priority the support of coordination functions and workflow interoperability points the way towards collaborative business environments. Though WfMC, Workflow Management Coalition, specifies the abstract interoperability, differences such as workflow concept models, ontology etc. cannot be dealt with effectively because the specification is only technical. On the other hand, portal technology focuses on the integration of information and application services customized according to roles. It can provide support for the interoperability of workflows. In this paper, workflows are integrated with portal technology. And a role centric collaborative environment is proposed which is a way out for problems existing in workflow interoperability.
