Abstract
In this paper, we present a tool that preserves phase consistency from specifications to the design phase by reverse engineering UML activity diagrams, designed from scenario specifications, back to scenarios to ensure that all of the original scenarios can be recreated. We use a set of action and action-link rules to specify the activity and scenario diagrams in order to provide consistency and rigor. Given an activity diagram depicting a common telecentre process es, we present an algorithm that follows this set of action and action-link rules to reverse engineer this activity diagram back to their set of scenarios. The validation of this algorithm is achieved when, given a set of activity diagrams, the algorithm is able to recreate the original set of scenarios. Thus, all original specifications, in the form of scenarios, are ensured to be encapsulated within their activity diagram.
