Solution cost appraisal
. Identification of the anticipated cost of incorporating

accomplish the change proposal, as well as modifications to task scheduling and 
milestone achievement.
5. 
Perceived benefit appraisal
. Identification of the anticipated benefits derived 
from the authorization of the proposed change in terms of stakeholder satis-

resulting from the experience gained, etc. In a contracted arrangement, the 
customer should fund any costs associated for incorporating a change deemed 
beneficial. If the cost is prohibitive, then the perceived benefits do not exceed 
the cost of the change.
