Implementing and Proving a Solution

Introduction

The Systems Approach also requires that the system be proved. In Systems Engineering this is called verification and validation. All of the system principles come into play in proving the system.

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, pp. 691-709) provides a comprehensive guide to the methods of both system verification and system validation.
