4.2.1 Requirements Verification Matrix (RVM)
A Requirement Verification Matrix (RVM) is usually composed of (1) a requirement identification code, (2) requirement traceability to higher level documents, (3) verification methods to be used, (4) the stage(s) where verification takes place and (5) the verification procedure identification code. Verification methods often listed in the RVM are Analysis, Inspection, Demonstration, Testing and Certification (see typical RVM structure in Figure 4.1).
The following guidance is proposed in order to assign a specific verification method to a given system requirement:
Verification by Analysis
Heuristically, a system analysis method may be used:
Verification by Inspection
Heuristically, a system inspection method (illustrated in Figure 4.2) typically includes the use of human senses (e.g., sight, hearing, smell and/or touch) or simple physical tools for manipulation or mechanical and electrical gauging and measurements ...
