Consider a project to produce custom door moldingsfor GMC Acadia cross-over vehicles, described inTable 7.4. a. If you start the project immediately, when will it be finished?b. You are interested in completing your project as soon aspossible. You have only one option. Suppose you couldassign Employee A, currently assigned to activity G, tohelp Employee B, currently assigned to activity F. Eachweek that Employee A helps Employee B will result inactivity G increasing its time by one week and activity Freducing its time by one week. How many weeks shouldEmployee A work on activity F?
G 1 A project management team is conducting the activity sequencing for a new project. The team has determined that Task A takes 3 days. Task B is dependent on Task A finishing and has a duration of 1 day. Task C takes 4 days. Task D is dependent on Task C starting and has a duration of 7 days. Task E is dependent on both Task C and Task D finishing and has a duration of 2 days. Task F is dependent on both Task E and Task B finishing and has a duration of 4 days. What is the critical path and duration of the project?
