CHAPTER 9 
Software Requirements Management
requests are design changes that affect the software architecture or implementation 
and are considered necessary to achieve specified software requirements.
The project change control board is responsible for authorizing change propos-
als. This mandates that the impact of a proposed change on project and technical 
plans be socialized with important stakeholders whom may be impacted by the 
change. A technical change impact statement must ensure that the proposed change 
can be accommodated within the augmented project cost and schedule resources. 
It may be possible to negotiate the elimination or adjustment to other software 
requirements if the project cost and schedule objectives are to remain unchanged.
The technical change control board is responsible for authorizing change 
requests that are proposed to affect a change in a previously specified element of 
the software product architecture. A change request represents suggested modifica-
tions to the software architecture definition that remediate obstacles, complexity, or 
obscurity with elements of the software architecture. Change requests should sim-
plify software implementation and test efforts or resolve architectural specification 
flaws and imprecision.
