27. © 2005 by Prentice Hall 3-27 Estimating Task Duration PERT: Program Evaluation Review Technique Technique that uses optimistic (o), pessimistic (p), and realistic (r) time estimates to determine expected task duration Formula for Estimated Time: ET = (o + 4r + p)/6

29. Critical Path Analysis Critical path method (CPM)—also called critical path analysis—is a network diagramming technique used to predict total project duration. A critical path for a project is the series of activities that determine the earliest time by which the project can be completed. It is the longest path through the network diagram and has the least amount of slack or float. –Slack or float is the amount of time an activity may be delayed without delaying a succeeding activity or the project finish date. The longest path or the path containing the critical tasks is what is driving the completion date for the project.

30. Figure 4-7. Critical Path Calculation for Project X

31. What Does the Critical Path Really Mean? The critical path shows the shortest time in which a project can be completed. If one or more of the activities on the critical path takes longer than planned, the whole project schedule will slip unless the project manager takes corrective action. For example: Apple Computer team members put a stuffed gorilla on top of the cubicle of whoever was in charge of a critical task, so they would not distract him or her.

32. Figure 4-8. Who’s Stuck With the Gorilla This Week?

33. Growing Grass Can Be on the Critical Path The fact that its name includes the word “critical” does not mean that the critical path includes all critical activities. Frank Addeman, executive project director at Walt Disney Imagineering, explained in a keynote address at the May 2000 PMI-ISSIG Professional Development Seminar that growing grass was on the critical path for building Disney’s Animal Kingdom theme park. This 500-acre park required special grass for its animal inhabitants, and some of the grass took years to grow. So, growing grass was driving the completion date of the theme park; not what most people would think of as a critical activity.

34. Using Critical Path Analysis to Make Schedule Trade-offs It is important to know what the critical path is throughout the life of a project so that the project manager can make trade-offs. If one of the tasks on the critical path is behind schedule, should the schedule be renegotiated with stakeholders, or should more resources be allocated to other items on the critical path to make up for that time? It is also common for project stakeholders to want to shorten project schedule estimates, so you need to know what tasks are on the critical path.

35. Questions on the Critical Path Can there be more than one critical path on a project? Can the critical path on a project change?

36. Schedule Compression Techniques Crashing is a technique for making cost and schedule trade-offs to obtain the greatest amount of schedule compression for the least incremental cost. –If two critical tasks each take two weeks, and it will take $100 to shorten Task 1 by a week and $1,000 to shorten Task 2 by a week, shorten Task 1. Fast tracking involves doing activities in parallel that you would normally do in sequence. –Instead of waiting for Task 1 to be totally finished before starting Task 2, start Task 2 when Task 1 is halfway done. Schedule compression often backfires by causing cost, human resource, and quality problems, which lead to even longer schedules.

37. Project Buffers A project buffer is additional time added before the project’s due date to account for unexpected factors. Kristin learned from past projects that no matter how well you try to schedule everything, it can still be a challenge to finish on time without a mad rush at the end, so she included a buffer in their project schedule.

38. © 2005 by Prentice Hall 3-38 Using Project Management Software Many powerful software tools exist for assisting with project management. Example: Microsoft Project can help with Entering project start date. Establishing tasks and task dependencies. Viewing project information as Gantt or Network diagrams.
