To reduce the likelihood of not meeting big commitments, Scrum uses a) Timeboxing so the planned events can happen on time. b) Timeboxing so the commitments will have additional buffer of time. c) Timeboxing so the events cannot exceed a predetermined amount of time.

C) Timeboxing so the events cannot exceed a predetermined amount of time. Scrum controls the risks associated with long term planning and big commitments by constraining the product development into shorter iterations called Sprints. Each Sprint is strictly time-boxed so they expire on the predetermined date no matter what. By timeboxing, the risk of pursuing a wrong direction is limited to the cost of one Sprint. Correct answer is ‘c.’
