A comparison tool compares metadata that describes an original workflow and metadata that describes a customized workflow. The original workflow and the computer application provide original functionality. The customized workflow is a modified version of the original workflow. The customized workflow and the computer application provide customized functionality. Analysis results, such as a report, are generated that represent the customized functionality. The comparison tool may further compare the original workflow metadata and customized workflow metadata with metadata that describes an updated original workflow. The updated original workflow and an updated version of the computer application provide updated functionality. Analysis results may be generated that represent the customized functionality merged with updated functionality, and a merged workflow may be created. A workflow editor may generate the metadata by associating step-specific metadata, such as origin metadata, type-of-step metadata, and dependency metadata, with individual workflow steps in the workflows.
