Verification Evidence Categorization & Review Discussions
Verification Evidence Categorization for Spacecraft Reviews
Engineering reviews rarely fail because evidence doesn’t exist.
They fail because teams use the same evidence to mean different things.
The OMI Evidence Taxonomy Quick Reference — Momentum Wheels provides a concise, non-prescriptive orientation to how verification evidence is commonly categorized and discussed for reaction wheel and momentum wheel assemblies during spacecraft reviews.
This two-page quick-reference reflects observed industry practice, not requirements. It is designed to help engineering teams align terminology during technical discussions—before ambiguity turns into dispute.
What This Reference Covers
This quick reference organizes commonly cited verification artifacts into four evidence categories as they are typically discussed in reviews:
- Analysis — predictive models, simulations, and analytical assessments
- Test — qualification, characterization, and performance testing
- Inspection — physical, assembly, and configuration verification
- Heritage — prior flight use, fleet history, and qualification lineage
- Each category includes 7-8 representative examples drawn from real spacecraft momentum wheel review contexts.
Who This Is For:
- Systems engineers preparing for spacecraft design reviews.
- QA leads organizing verification evidence.
- Program managers coordinating customer reviews.
- New team members learning spacecraft verification practices.
- Anyone working with reaction wheel or momentum wheel verification.
How This Reference Is Intended to Be Used
- As a printable, laminatable desk reference during review preparation
- As a shared language aid during PDR, CDR, TRR, and qualification discussions
- As an orientation tool for new team members entering verification discussions
- As a neutral framing aid when evidence categories overlap or are debated
This document does not prescribe what evidence a program must produce, nor does it define verification sufficiency.
Why OMI Publishes This
OMI frameworks focus on how verification is discussed and interpreted, not how it is mandated. By making common evidence framing patterns explicit, teams can reduce friction, improve clarity, and keep reviews focused on substance rather than semantics.
This complimentary reference is an introduction to the OMI Verification Coverage Map for Momentum Wheels (VCM-MW) product line, which includes deeper frameworks, terminology guides, and implementation tools for spacecraft attitude control verification planning.
