An organization relies on its QA group to qualify its products. An adequate testing can be achieved relatively easily if your product is simple and does not involve multiple facets such as software, hardware, OEM components, and industry compliances including safety and environment. A product with multiple facets has increased product qualification complexity as multiple test teams get involved. It also becomes increasingly important to assure that all facets of the product are tested and there is no unintended test efforts duplication.
The RPS group at Hewlett-Packard has developed a technique that assures a high level of test effectiveness and efficiency and yields a high quality product. The technique involves identifying the quality attributes (test types) that must be tested for a product. These test types include Functionality, Usability, Reliability, Installation/Deployment, Safety, and Regulatory and form the horizontal test vector. To make sure that the product components are adequately tested before they are integrated, a vertical test vector representing development stages including Unit, Module, Component, System, and Solution and Beyond is also established. The two vectors together yield a highly effective and efficient â€œTest Landscapeâ€ that is used to determine test ownership and track test status from the very early stage in the product development lifecycle to the final release. The technique is being used by the group and has made test management simple yet efficient. It has also assured the management teams that the testing is effective and efficient. The Test Landscape has become a part of the Product Development Lifecycle and is reviewed at various checkpoints during the development. The group has also developed a roles and responsibility model that assures that the Test Landscape is properly executed to yield the maximum benefit.
