Abstract: Disclosed are a method and a system for comparing established workflows against a workflow pattern to determine their degree of compatibility with this workflow pattern. In the method and system, compatibility scores between established workflows and a workflow pattern can be determined. To determine the compatibility score between a workflow pattern, which comprises first tasks, and an established workflow, which comprises second tasks, equivalent tasks in the established workflow can be identified. Then, dependency matrices can be constructed for the first tasks in the workflow pattern and the equivalent tasks in the established workflow. These dependency matrices can be compared in order to identify any dependency relation matches in corresponding task pairs. Values can be assigned to the dependency relation matches and compatibility scores can be determined based on the sum of those values.
