If you need to shorten the total project time 18 weeks to a shorter time period due to a market change, which activity should be "crashed" first, assuming crash cost is important for the change? Why do you pick the activity? (b) If we decide to crash Activity D by two weeks due to a company request, which of the following statement is the most correct one and why? bl. The project's schedule will be reduced by two weeks b2. The available slack on the non-critical paths will increase b3. A new critical path may appear after the crash b4. All of the above b5. bl and b2 only
