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).
