Which of the following statements is false regarding the impact of uncertain activity time? there may be a delay in the actual project completion time. there may be a delay in the expected project completion time. the critical path is independent of the outcome of the uncertain activity times. there may be a shift in the critical path.

The critical path is independent of the outcome of the uncertain activity times.

Explanation:

Uncertainty is an inherent aspect of project management. When the model is constructed and the critical path is determined, all activities are future events. Inputs to the project management analysis include for each activity estimates of the time duration, estimates of resource usage and estimates of costs. Of course, there may also be uncertainty with regard to the activities that comprise the project and the precedence relations among them. In many cases everything about the project is to some extent uncertain, but in this lesson we consider only the uncertainty of activity durations. There are many human and political factors that bring to question the time estimates provided by persons associated with a project . In a project environment, all uncertainty will eventually be revealed, assuming that the project is actually finished. The revelation occurs as time passes and as activities are started, performed and finished. At times after the project has begun but before it is complete, the manager may take action to change many features of the model that are not yet completed, perform new analyses, and take corrective action where appropriate. Project management is far more than determining the precedence relations, estimating resources and costs, and computing the critical path. Estimates made before the project begins must surely be adjusted to account for the realization of results. The ability to make adjustments after the project has begun partially helps with the difficulties associated with uncertainty. Plans can change. Decisions may shift as the future is revealed by the passage of time. The critical part is dependent on the uncertain activity times.
