- Consider the following activities for a project. Answer the questions below. a. Assume the durations given are high confidence, create a network chart (don’t considerresources yet), and identify the critical path. What is the duration of the project? b. You aren’t quite ready to apply the critical chain project management yet, but you do want toeliminate multi-tasking. Eliminate any resource contention in your network. Identify the criticalpath now? What is the duration of the project? c. Apply the critical chain project management approach to this project. Create a new view ofyour project network, include a project buffer and any needed feeding buffers. What is the criticalchain? What is the duration of the project now?arrow_forwardPlease, I need help because I have no idea how to do any of these. 11. Building a backyard swimming pool consists of nine major activities.
