Draw a CPM network for the project. an overview for the project by computing the duration for each path. c. What is the critical path? What is the project's estimated duration? 8. In Problem 7: a. Draw a CPM network for the project. b. Compute the EF, LF, and slack for each activity. Write the values on the CPM network. c. What is the critical path and its duration? 9. A company is about to begin a project to design a production process for producing a new product Management has estimated that the project should require about 45 days to complete. Although 45 days seemed very short to the process engineers at first, after some discussion it was concluded that they probably could meet the deadline because the product and its processes were so similar to the present processing technologies in use at their plant. These activities, their precedence relationships, and their durations were estimated by the engineers
