The WestWind System Engineering (SE) Test and Evaluation (T&E) team gets involved early in the requirements definition and development phases to ensure the system requirements are verifiable.
Like all systems engineering planning activities, careful attention to test planning can reduce program risk. The key test planning document is the Test and Evaluation Master Plan (TEMP). The verification activities of the systems engineering process are performed to verify that physical design meets the system requirements. Prior to beginning the testing phase, a Test Readiness Review (TRR) is held to ensure safety compliance, equipment readiness, and personnel resources and test procedure accuracy to expedite test completion.
The Requirements Verification Matrix (RVM) developed by the system engineers is used to generate a Test and Evaluation Master Plan (TEMP) and the Test Verification Matrix (TVM) which is used to ensure requirements are traced to test requirement at the appropriate level of system integration. The T&E group participates in Test Plan Working Groups (TPWGs) and Test Integration Working Groups with customers and users to review and update the TEMP as necessary, coordinate processes, identify and mitigate any risks, and resolve test cost and scheduling issues.
Test Engineering’s role is to develop and execute test methodologies, plans, and procedures to ensure the developed system meets the specified product requirements and customer needs. Our Engineers have a broad knowledge of the products and systems being developed along with the tools and techniques required to evaluate the products. They are members of the project team from the requirements development phase to system life cycle support. The requirements and test verification matrices are developed, maintained and used by the Test and Evaluation team to ensure a bottom-up requirements compliance and system performance. Traceability between requirements, method of test, and test results are maintained in the product’s requirements database.
Test results are then captured and linked to the requirement(s) verified by each specific activity. Performing a trace analysis within the database produces a verification report showing performance requirements juxtaposed with test results and a summary of whether the observed performance satisfies the pass/fail criterion for each individual requirement.
The T&E Engineers are also responsible for defining functional, operational and environmental tests to include:
- Mechanical and Electrical Thermal
- Dust Particle
- Salt Fog and Spray
- Cleaning Solvents
- Open Flame and Burn
- Static and Dynamic Shock
- Loads and Tensile Strength
- Crash Loads Testing
- 3-Axis Vibration
- 3-Axis Shock
- Gun Shock
- Live Fire Testing
- Endurance and Life Cycle Testing
- Electromagnetic Interference and Compatibility
