The execution module and the test planning module are definitely the most valuable features. The rest we use for traceability, but those are the two modules that I cannot live without.
OpenText ALM / Quality Center offers extensive customization in the Defect Tracking module, supporting traceability between requirements, testing, and defects. It integrates with automation tools, enhancing quality and efficiency. It includes dashboards for project management but only supports Internet Explorer, limiting usability. It's not optimized for Agile practices, complicating Agile management. Cross-project reporting lacks features, requiring specific browser and admin access, highlighting the need for improved integration and reporting capabilities.
