Systems Engineering Glossary
Streamlining, adapting, or otherwise changing an established approach or process to address a specific application.
|Technical Performance Measures|
|Technology Readiness Level (TRL)||
A graded scale of technology maturity levels useful in assessing technical risk and implementation viability.
A test case is a set of controlled conditions or variables that are executed to determine whether a system under test satisfies requirements.
The person responsible for planning the test life cycle activities and deliverables, providing technical focus to the test team, and developing and managing to the schedule.
A document describing the detailed approach for performing testing at each test level. It defines the detailed set and sequence of specific test cases to be executed, the organizational roles and responsibilities, and associated test schedules.
|Test Readiness Review (TRR)|
A process to show the relationships (upwards and downwards in a requirements hierarchy) between sources, decomposition, and implementation of requirements.
A trace deficiency exists when a requirement statement cannot be fully traced back to its authorizing source (orphan), or has no path for realization (childless parent).
A visible relationship among two or more logical entities, for example, requirements.
A process to evaluate system alternatives against specific evaluation criteria in order to select the best solution.
The decision-making actions to select the best alternative among multiple options.
The process of moving from one life cycle stage or level of the system hierarchy to another. The term is often used to refer to the shift from the development environment to the operational environment.
