OpenText ALM / Quality Center offers customizable defect management and seamless integration with HPE products, enhancing test management and traceability. It provides a comprehensive view of project management with test execution and defect linkage. Despite enhancing test organization, it lacks support for Agile tools, limits cross-project reporting, and only supports Internet Explorer. The setup requires administrative rights and does not support Chrome or Mac OS, posing challenges in restricted environments.
