Requirement Code Definitions : Requirement Code Definitions
Verification Cross Reference Index (VCRI) Code Definitions : Verification Cross Reference Index (VCRI) Code Definitions Inspection (I). Verification by examination of the item, reviewing descriptive documentation, and comparing the appropriate characteristics with a predetermined standard to determine conformance to requirements without the use of special laboratory equipment or procedures.
Analysis (A). Verification by technical evaluation using mathematical representations, software code reviews, charts, graphs, circuit diagrams, data reduction, and/or representative data.
Demonstration (D). Verification by operation, movement, and/or adjustment of the item under specific conditions to perform the design functions without recording of quantitative data.
Test (T). Verification through systematic exercising of the applicable item under appropriate conditions with instrumentation to measure required parameters and the collection/analysis/evaluation of quantitative data to show that measured parameters meet specified requirements.
Not Verified (N). Requirement not verifiable.

CWD Device Performance CriteriaWhat is it? : CWD Device Performance Criteria What is it? Criteria Items are Derived from CWD Requirements
Criteria Item Values are Obtained for each Device Under Test (DUT) using the Requirements Verification Results
Criteria Items Allow All the DUT to be Compared via a Common Nomenclature
CWD Device Performance CriteriaDerivation Example : CWD Device Performance Criteria Derivation Example Criteria Number: 1
Device Criteria: Size/Weight
Associated Requirements: 2, 18, 47
Requirement 2:
Weighs less and is smaller than a standard refrigerator.
Requirement 18:
Weighs less than 500 pounds and operates on standard 110-volt current.
This requirement also associates with Criteria 3a: AC Power Source
Requirement 47:
Weighs between 5 and 10 pounds, is durable, and meets all applicable military specifications.
This requirement also associates with Criteria 31: Equipment Durability
