Verification Methods (TAID)

NASA defines four verification methods (SP-6105 SS 5.3). Applied to cloud operations:

Each requirement in the verification matrix specifies which TAID method(s) apply. Complex requirements may use multiple methods (e.g., Test + Inspection for a security requirement).

Document Templates

Each NASA document type maps to a cloud operations equivalent:

Document Template Structures

Heading outlines for the three critical document types. Executors producing these documents should follow this structure.
