Abstract
A method supporting work processes involving activities such as generation, alteration and authentication of documents. For each activity, the relationship between that activity and each other activity is defined in terms of at least one dependency from a plurality of dependencies. Each activity has a plurality of possible independent user and system states, for example three for the user states and three for the system states. The independence of the user and system states improves flexibility by introducing a mechanism to support reasoning over the process flow, so that discrepancies can be used to maintain a record of any mismatch.
