You have been hired as the project manager by a leading financial services company and are in the planning phase. Your task is to sequence four projects in a way that minimizes the total cost of delay. Consider the build duration and the value (revenue per week) of each project. Determine the best sequence for these projects. In addition, calculate the total cost of delay based on your sequencing. (note: enter the total cost of delay in whole number please – no decimals, no cents, no comma, no dollar sign). Project Build Duration (weeks) Value (revenue/week) Project A 2 10,000 Project B 4 40,000 Project C 6 90,000 Project D 8 80,000   Recommended Sequence: First  [c1] Second  [c2] Third  [c3] Fourth  [c4] Total Cost of Delay (enter whole dollars):  [c5]
