Note: See Appendix I for an outline of the Verification and Validation Plan. The matrix shown here (Table E-1) is Appendix D in that outline.

When developing requirements, it is important to identify a validation approach for how additional validation evaluation, testing, analysis, or other demonstrations will be performed to ensure customer/sponsor satisfaction.

There are a number of sources to draw from for creating the validation plan:

• ConOps
• Stakeholder/customer needs, goals, and objectives documentation
• Rationale statements for requirements and in verification requirements
• Lessons learned database
• System architecture modeling
• Test-as-you-fly design goals and constraints
• SEMP, HSIP, V&V plans

Validation products can take the form of a wide range of deliverables, including:

• Stakeholder evaluation and feedback
• Peer reviews
• Physical models of all fidelities
• Simulations
• Virtual modeling
• Tests
• Fit-checks
• Procedure dry-runs
• Integration activities (to inform on-orbit maintenance procedures)
• Phase-level review solicitation and feedback

Particular attention should be paid to the planning for life cycle phase since early validation can have a profound impact on the design and cost in the later life cycle phases.

Table E-1 shows an example validation matrix.
