Joe and Nol have just gotten engaged. Seeing as they are both business stu- dents, they thought that they'd try to plan out their wedding preparation as a project. Here's the WBS they've determined is necessary for a simple but elegant wedding. Assume all durations are deter- ministic. Although perhaps not realistic to real wedding planning, use the stand- ard calendar in ProjectLibre or MS Project (activities occur on business days and non-holidays only, 8 hours working time).

Please note that each question is independent and not built upon each other. (Ctrl) a) If Joe and Nol start wedding planning on October 1, 2020, when is the wed- ding day? b) What is the critical path? List all critical tasks in chronological order. c) Will the critical path change if Nol decides she needs two extra weeks for the Bridal Diet? If yes, what is the new critical path and when should the wedding be held? d) Assume that band auditions take twice as long as expected. Does this affect the wedding day? If yes, when should the wedding be held? e) If they want to get married on 2/14/2022, when do they have to start the wed- ding planning? f) Determine what predecessors need to be listed to make sure everything is done by the wedding day without needlessly checking things? Nol is going to be nervous enough without having to check to see if each of the 18 tasks are complete at the end!
