4.3 TOOLS FOR TRACING
The basic tracing method is to:
• uniquely identify the items to be tracked;
• record relationships between items.
ESA PSS-05-0 states that cross-reference matrices must be used to
record relationships between:
• user requirements and software requirements;
• software requirements and architectural design components;
• software requirements and detailed design components.
In addition, test designs should be traced to software components
and requirements.ssary when compilers do not check control flow, data
Tracing tools should
