A change request arrives proposing that a system add support for a new payment method. Which of the following activities would typically be part of the change impact analysis subprocess before this change is approved? Select all that apply.
Correct Answer
(1) Identifying which existing components and interfaces would need to be modified
(2) Estimating the cost and effort required to implement the change
(3) Assessing whether the change affects other systems that interact with this one
(4) Determining whether the change conflicts with existing requirements or constraints
Explanation
Change impact analysis typically involves identifying affected components and interfaces, estimating cost and effort, assessing effects on other interacting systems (especially important in a system-of-systems context), and checking for conflicts with existing requirements or constraints. These activities inform whether and how the change proposal should proceed.
