This topic is part of the Systems Approach Applied to Engineered Systems Knowledge Area (KA). It describes knowledge related to the implementation and proving of a preferred solution that may have been selected by activities described in the Analysis and Selection between Alternative Solutions topic. The activities that apply to an implemented solution during its operational life are described in Deploying, Using, and Sustaining Systems to Solve Problems topic and how systems fit into commercial and acquisition relationships in the Stakeholder Responsibility topic. Any of the activities described below may also need to be considered concurrently with other activities in the systems approach at a particular point in the life of a system-of-interest (SoI).

The activities described below should be considered in the context of the Overview of the Systems Approach topic at the start of this KA. The final topic in this KA, Applying the Systems Approach, considers the dynamic aspects of how these activities are used as part of the systems approach and how this relates in detail to elements of systems engineering (SE).

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. In the systems approach this topic pertains to the more abstract level of providing evidence that the system will accomplish what it was meant to do. In systems engineering this topic pertains to providing quantitative evidence from tests and other methods for verifying the performance of the system.

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 the systems approach this topic pertains to the more abstract level of making sure the system meets the needs of the stakeholders. In systems engineering, this topic pertains to the detailed demonstrations and other methods to satisfy the stakeholders.

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