In "End of Watch", Charlie is trying to understand the possible paths taken by a murder suspect. He realizes that he needs to consider the paths of both the suspect and the victim. He refers to and discusses Critical Path Analysis (CPA) as a mathematical way of finding the most efficient way to complete a set of tasks. In the case of the victim, it was the timeline for the day he was killed. In this activity, students will apply CPA to making a schedule.
