The systems approach requires that the system be proved. In systems engineering this is called verification and validation. The following sections of this article briefly discuss the nature of system proving from a systems approach viewpoint. Any of the activities described below many need to be considered concurrently throughout the systems' life, as discussed in the Applying the Systems Approach topic.

Proving the System Overview

This topic covers both the sub-topics of verification and validation.

Verification

Verification is the determination that each element of the system meets the requirements of a documented specification (see principle of elements). Verification is performed at each level of the system hierarchy (see principle of grouping and System Analysis).

Validation

Validation is the determination that the entire system meets the needs of the stakeholders. Validation only occurs at the top level of the system hierarchy.

In a systems engineering context, Wasson (2006, 691-709) provides a comprehensive guide to the methods of both system verification and system validation.

Linkages to other topics

The systems approach topic is linked to the systems engineering topics of verification and validation.
