  1. Fill in the blank cells under Crash Differentials.
  2. Instead of the scheduled 7 weeks, Task B took 9 weeks. Which task or tasks should be crashed to make up the lost time, at minimum cost? Explain.

Assignment Expectations

  1. There are no page limits. Write what you need to write, neither more nor less. Make each sentence count! (Having said that; it’s unlikely that one page would be enough, and very likely that eight pages would be too much.)
  2. Ensure that your answer reflects your detailed understanding of the theory and techniques taught in this module.
  3. References and citations are required. This requirement can be satisfied by citing the module Home page.
