Strategy

Change avoidance
Change tolerance

Description

The software process includes activities that anticipate possible changes before significant rework is required
The process is designed so that changes can be accommodated at relatively low cost

Correct Answer

(1) Change avoidance,The software process includes activities that anticipate possible changes before significant rework is required
(2) Change tolerance,The process is designed so that changes can be accommodated at relatively low cost

Explanation

Change avoidance: the process includes activities that anticipate possible changes before significant rework is required — e.g. prototyping. Change tolerance: the process is designed so that changes can be accommodated at relatively low cost — e.g. incremental development. Incremental delivery supports both: it avoids premature commitment to requirements for the whole system, and it allows changes to be incorporated into later increments at relatively low cost.
