Progress curve. Figure 8.10 shows the resource requirements (unleveled) for the arrow diagram of Figure 8.6. assuming that each activity will start at its EST.

a. Draw the modified bar chart assuming that each activity will start at its LST, and show the (unleveled) resource requirements corresponding to this formal.

b. Assume that resource units active on a day are linearly proportional to project value added on that day. Plot the S-curve for the project under the assumption of an early start for each activity. and, on the same diagram, the S-curve under the assumption of a late start for each activity. Let the x-y axes of the plot be expressed in percent project time completed and percent project value completed, respectively.

c. Actual progress on the project has been calculated at the end of days 5, 10, and 13. The percent of total project value in place at these times is 10, 20, and 40.

(1) Plot the S-curve for actual progress on the diagram of part (b ). At the end of day 13. what would be a fair estimate of the time to complete the project?

(2) What is your subjective assessment of the chances that the project will be completed on time?
