This article considers the activities of the systems approach related to the implementation and proving of a prefered solution in detail. Any of the activities described below may need to be considered concurrently with activites the other activities of in the Systems Approach. The final article in this knowledge area, 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.
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.
Linkages to other topics
The systems approach topic is linked to the systems engineering topics of verification and validation.
