2.2 VVT ACTIVITIES DURING DEFINITION

The purpose of the system Definition phase is to formulate the system operational concepts and create the system requirements, usually documented in the form of specifications or models. One purpose of VVT activities during the system Definition phase is to ensure that the system requirements and system concepts accurately reflect the real-world operational needs. VVT activities also lay the foundation for further VVT planning based on fully understanding the system requirements and concepts. The VVT tailoring process and the VVT strategy determination typically occur at the beginning of the system Definition phase. The VVT process model should be initialized with known or estimated parameters. The following sections define specific VVT activities that are appropriate for the system Definition phase.

2.2.1 Generate Requirements Verification Matrix (RVM)

Objective

The objective of this VVT activity is to determine (1) the method of verifying each system requirement, (2) when it will be done within the lifecycle of the system and (3) the specific procedure according to which the verification will be accomplished.

Description

Creating or updating the Requirements Verification Matrix (RVM) is an ongoing activity that may start as early as the creation of a response to a Request For Proposal (RFP) or with the first release of the test and verification plan. The RVM is a table listing the following elements (see example in Figure 2.1):
