Test and Verification Management
Test and verification management are the processes and procedures to suitable critique the product (hardware or software) or processes (production). This is risk identification and mitigation activity as it attempts to quantify quality attributes of the product that may cause concerns with the customer during application. Testing and verification is also part of project management in that the results are often used to confirm contractual obligations are met, and thereby are part of project closure. Testing and verification management contain, planning and control, analysis and design, execution, reporting and closing activities. Hardware testing may include environmental stimuli (multiple simultaneous such as thermal and vibration) as well as testing the product to the extremes of functionality.
In testing closure the objective and specific deliverable items from the testing are compared to the actual achievements and deliverables. The testing documentation is stored in a way that is easily retrievable along with the information on the product iteration the specific test cases were conducted. The test environment configurations are archived so these can also be retrieved at a later date should that be needed. Lessons learned are recorded from which the team will apply at some future date.
During test execution the tests are conducted on the product. Each of the test conditions and test environments are used to conduct the defined tests. Sometimes there will be spontaneous testing conducted, that is not one that was born out of the scope, plan or test analysis, but from what is learned in the process of conducting the test. Test execution will also be responsible for re-testing as perhaps the results of the test were some anomaly based upon the test configuration, or to learn more about the failure to be able to accurately report the details of the conditions that caused the failure. These are clues the developers will use to find the reason for the failure (hardware or software). Test execution address regression testing, that is testing of old parts of the product that have not changed, but require testing since the product has changes – this is largely associated with software.
Test Exit, Metrics and Reporting
Testing produces data from which an informed decision about the product can be made. These metrics will inform the team and other stakeholders the product’s suitability for release or production. Test metrics such as failure rates and severity remove some of the uncertainty from the launch. This phase of the testing produces reports where this information will reside allowing the project manager, stakeholders and executives to decide whether to launch or not based upon the results.
Test Planning and Control
To be able to test requires an understanding of the objectives of the project and customers. This understanding makes it possible to discern specific risks and clarify the scope of the testing to make assessment of those risks possible. Test planning will uncover and define the best test strategy along with discovering the talent and equipment required. Additionally, the planning will evoke key metrics or measurements from which the testing and results will be evaluated.
Test Analyze and Design
In test analysis and design, specific test conditions are identified from which the details of the testing will be created. This will require inputs such as product requirements and drawings, specifications, system descriptions and interfaces to other components and typical and extreme applications of the product. This will generate specific test methods, criterion, and metrics that will lead to detailed test cases along with the input data (test conditions) for the test. There is a strong connection between the product requirements and design documentation and the test details.
Test and verification management – techniques for ensuring the product design, material and, where applicable, manufacturing processes culminate in meeting the customer’s needs. At the minimum verification serves to confirm or refute the product meets requirements. However, there are many other approaches to testing iterations of the product through the development process. This includes software testing, which consists of processes and techniques that is coupled with the development effort to ensure the product quality over prototype iterations and the full lifecycle of the product.
