Description
Importance
Requirements Baseline Verification Tasks
Verify software 
requirements 
specifications
Confirm that every software requirement can 
be traced to a legitimate stakeholder need or 
expectation.
Essential 
(mandatory)
Confirm that every requirement is unique, quantifiable, 
and testable.
Confirm that the set of requirements are collectively 
consistent and nonrepetitive.
Confirm that software requirements have been stated 
in a manner consistent with requirements trade-study 
records.
Verify software 
interface 
specifications
Confirm that every external interface is specified in 
a manner that is beneficial to the data processing 
transactions.
Essential 
(mandatory)
Confirm that interfaces provide the data or  
information necessary to support data processing 
transactions.
Confirm that interfaces do not detract or interfere with 
effective or efficient data processing transactions.
Verify operational 
models
Confirm that operational models accurately represent 
the operational or business process they are intended 
to portray.
Essential 
(mandatory)
Confirm that every element of the operational  
model is properly defined to prevent erroneous 
interpretations.
Confirm that operational behaviors establish the 
software measures of effectiveness and performance.
Verify 
requirements 
pedigree
Confirm that every requirement has been sanctioned 
by key stakeholders, including the project manager 
and software engineering team.
Important 
(advisable)
Confirm that the source of the requirement has been 
properly documented in the requirements traceability 
mechanism.
Confirm that every requirement is substantiated by the 
operational models.
