Verification, Validation, and Testing of Engineered Systems

2.4 VVT ACTIVITIES DURING IMPLEMENTATION

The purpose of the system Implementation phase is to create the elements of the system. Some elements may be purchased from other producers and therefore may require purchase specifications. Other elements may require detailed engineering design. Each element, whether purchased or built by the system producer, should be verified against its design and then tested to ensure its stand-alone compliance with its allocated requirements.

VVT activities during the system Implementation phase include detailed planning of the testing process as well as performing simulation, analysis or actual testing, mostly at the subsystem level, in order to verify detailed designs/specifications against requirements.

2.4.1 Preparing the Test Cycle for Subsystems and Components

Objective

The objective of this activity is to prepare the testing process for subsystems and components. This includes (1) planning the test process with the objective of specifying the elements necessary to perform and manage these tests, (2) preparing the infrastructure for executing the various tests, (3) designing the test cases for all relevant subsystems and components and (4) creating a test documentation infrastructure which will provide information to interested parties as test data accumulate throughout the test cycle.

Description

Testing subsystems and components during the Implementation phase is an integral part of the system-building process. It is usually not a stand-alone ...
