volume_mute
Which of the following are factors that help evaluate the relationship between a system and its environment, used to predict the number of change requests? Select all that apply.
Correct Answer
(1) The number and complexity of system interfaces
(2) The number of inherently volatile system requirements, especially those reflecting organizational policy
(3) The business processes in which the system is used
Explanation
Three key factors evaluate a system's relationship to its environment: the number and complexity of interfaces (more interfaces mean more likely interface changes); volatile requirements tied to organizational policy (more likely to change than stable domain requirements); and the business processes the system supports, since evolving processes generate change requests.
