Integrating Engineering Specialties Into the Systems Engineering Process ops a verification program considering its cost,
schedule, and risk implications. No one program can be
applied to every project, and each verification activity
and product must be assessed as to its applicability to a
specific project. The verification program requires
considerable coordination by the verification engineer,
as both system design and test organizations are
typically involved to some degree throughout.
6.6.1 Verification Process Overview Verification activities begin in Phase A of a
project. During this phase, inputs to the project's
integrated master schedule and cost estimates are
made as the verification program concept takes shape.
These planning activities increase in Phase B with the
refinement of requirements, costs, and schedules. In
addition, the system's requirements are assessed to
determine preliminary methods of verification and to
ensure that the requirements can be NASA Systems Engineering Handbook

verified. The outputs of Phase B are expanded in Phase
C as more detailed plans and procedures are prepared.
In Phase D, verification activities increase substantially;
these activities normally include qualification and
acceptance verification, followed by verification in
preparation for deployment and operational verification.
Figures 32a and 32b show this process through the
NASA project life cycle. (Safety reviews as applied to
verification activities are not shown as separate
activities in the figures.)
The Verification Program Concept. A verification program should be tailored to the project it supports. The
project manager/system engineer must work with the
verification engineer to develop a verification program
concept. Many factors need to be considered in
developing this concept and the subsequent verification
program. These factors include:
