The correct answer is C. Time and cost will increase, and scope will remain. Adding quality testing mid-project increases both time and cost by introducing new activities and resource needs, while the scope of defined deliverables remains unchanged.

Question

A project manager failed to include quality testing in a software development project plan and must now add it while the project is underway. Which of the following BEST describes the relationship that quality will have on the triple constraint?

Options

  • ATime, cost, and scope will decrease.
  • BTime and scope will remain static, and costs will increase.
  • CTime and cost will increase, and scope will remain
  • DTime will remain static, and scope and costs will increase.

Why each option

Adding quality testing mid-project increases both time and cost by introducing new activities and resource needs, while the scope of defined deliverables remains unchanged.

ATime, cost, and scope will decrease.

Adding activities cannot decrease time, cost, or scope; all three would either increase or remain the same.

BTime and scope will remain static, and costs will increase.

Time cannot remain static when new testing activities are inserted into the project schedule.

CTime and cost will increase, and scope will remainCorrect

The triple constraint links scope, time, and cost such that changes to one affect the others. Introducing quality testing adds new activities to the schedule, extending project duration (time increases), and requires additional labor or tools (cost increases). Scope - the set of deliverables - does not change because quality testing validates existing deliverables rather than adding new ones.

DTime will remain static, and scope and costs will increase.

Scope does not increase because quality testing is a process activity, not a change to the project's defined deliverables.
