A phase is a combination of associated activities that represent a distinct stage within a project. A phase can have distinct start and finish dates and include several stages of planning and work. Each project has a defined scope of work, such as a unique product or service. Some examples of phases within the scope of work for a project plan are conceptual engineering, pre-construction, and engineering.

Answer option A is incorrect. Concrete is an activity, not a project phase.

The difference between the buffer needed and the buffer remaining can determine whether corrective action is appropriate.

Answer option C is incorrect. This is not an accurate description of how the critical chain determines the need for corrective action.

Answer option B is incorrect. This is not an accurate description of how the critical chain determines the need for corrective action.

Management is asking Sam to use the judgmental methods to predict how the project will finish on time and cost. The judgmental forecasting method incorporates intuitive judgments, opinions and subjective probability estimates. Some examples of judgmental forecasting are as follows: Composite forecasts Surveys Delphi method Scenario building Technology forecasting Forecast by analogy

Answer option B is incorrect. Time series methods of forecasting use earned value management, moving average, extrapolation, linear prediction, trend estimation, and growth curve.

Answer option D is incorrect. The earned value management method is actually a part of the time series forecasting method.

Answer option C is incorrect. The causal/econometric methods use linear and non-linear regression, autoregressive moving average, and econometrics.

The float for Activity I is three days. The early start for Activity I is Day 17 and the late start for Activity I is Day 20. Therefore, the difference of the early start and the late start reveals the float as three days. It is possible, and acceptable, to use the difference of the early finish and the late finish to find the float, as the value will be the same amount.

Answer options B, D, and C are incorrect. These are not the valid calculation for the total float.
