The product manager laid out the activities required to design the circuit with their corresponding precedence relations, and obtained their typical durations. The PERT-CPM template is used to find the schedule of the project. The data is provided in the file below. The second and third sheets of this file also shows the application of the PERT-CPM template in scheduling the project. CLICK HERE TO GET THE DATA FOR IT COMPANY Which activity should be completed without interruption? If there are multiple such activities, enter the one with the longest duration. (Enter as a capital letter of the alphabet) After 20 days, the progress of each of the activities is measured and is provided below. Activities A and B are fully completed. Activity C is 80% complete. Activities D, E, F, and G are each 20% complete. All other activities are not yet started. We would like to plan for the remainder of the project to be finished the soonest given the current progress. Compare this plan and the initial plan of completing the project (the one given in the Excel file). Is the project ahead or behind schedule? (Enter the word "ahead" or "behind") By how many days is the project ahead or behind? (Enter as a positive number with one decimal place) Assume that each individual activity would cost $2000 to be fully completed. By day 20, a total of $6,000 is spent. Has the company spent over or under the expected amount (from the initial plan in the Excel file) by day 20? (Enter the word "overspent" or "underspent") By how much is the project overspent or underspent? (Enter as a positive number rounded to the nearest dollar)
