2. Joe and Noël have just gotten engaged. As they are both business students, they thought they'd try to plan 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 deterministic. Although perhaps not realistic to real wedding planning, by using the standard calendar in Project Libre (use default working days in software). Task ID Task Name Duration Predecessor 1 Begin Wedding Planning (milestone) 0 days --- 2 Select Site&Date 3 wks 1 3 Hire Officiant 1 wk 2 4 Hire Caterers 2 wks 1 5 Pick Menu 4 days 4 6 Order Invitations 2 wks 2,5 7 Sent Invitations to Guests 1 wk 6 8 Collect RSVPs 6 wks 7 9 Tell Caterer headcount & Order food 1 wk 8 10 Shop for Wedding Gown 4 wks 1 11 Select Bridesmaids Dresses 4 wks 10 12 Bride goes on Diet 6 wks 10 13 Get Wedding Gown altered 2 wks 12 14 Get Bridemaids' Dresses altered 4 wks 11 15 Order Flowers 2 wks 11 16 Audition Mariachi Bands 3 wks 2 17 Select and Sign on Band 1 wk 16 18 Select Grooms Tux 2 days 10 19 Select Best Man& Usher's Tuxes 2 days 18 20 Wedding Day (milestone) 0 days ???? Based on this project, answer the following questions. Please note that each question is independent and not built upon the other. Will the critical path change if Noël 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? Assume that band auditions take twice as long as expected. Does this affect the wedding day? If yes, when should the wedding be held? Determine what predecessors need to be listed to make sure everything is done by the wedding day without needlessly checking things? Noël is going to be nervous enough without having to check to see if each of the 18 tasks is complete at the end!
