EN Use cases are a scenario-based technique used to express functional requirements from the user perspective. They are often elicited using a top-down approach by first identifying their goals and later documenting their scenarios. In the paper, we investigate the possibility of supporting analysts in progressing from definitions of use-case goals to full documentation of their scenarios. We propose a semi-automatic approach to generate use-case scenarios based on use-case patterns. The proposed approach is a result of an empirical analysis of 217 use cases from 12 projects. The analysis revealed that a notion of use-case transaction could be used to organize use-case patterns into a catalog of patterns. We have implemented a prototype tool called UC-Sketch to illustrate the proposed idea. The acceptance of the proposed approach by its potential users was assessed through the use of Technology Acceptance Model.
