PERT considers activity costs and CPM does not. PERT can assign probabilities to activity times and CPM does not. CPM considers activity costs and PERT does not. 5 of 20 IIarrow_forwardYou are in charge of a project. Your team has determined that there are 7 activities to be completed. Here are the activities, the time to complete the activity and the immediate predecessor of the activity. Using this data 1) construct a Gantt Chart, 2) determine the time it will take to complete the project, 3) You are monitoring the progress of this project and discover that activity C is in danger of taking longer than planned due to funding issues. What options do you have to get the project back on track?
