  • It may be helpful here to ask students to compare the effort they believe necessary to manage this project to the effort they believe required to actually perform the physical tasks. Total cost might be a useful unit of comparison. One might expect the management cost to run 10% - 20% of the total.
  • It is helpful here to provide an expanded discussion of the activities.
  • A useful project management technique must contribute in all areas.
  • If students have been assigned a term project, this material can be covered early in the semester and the students asked to develop a plan for their project.
  • Students should be asked to explain why these requirements are appropriate.
  • This may be a good time to look, at least briefly, at alternative organizational structures. Certainly hierarchical and matrix structures should be examined. The role of information technology in each of the alternatives should be examined. The following several slides illustrate various organizational structures.
  • Given that a project is something the firm is relatively unfamiliar with, how does one go about determining the appropriate costs and times? You might point out that specifying the beginning and end points for an activity is often a difficult task. Work breakdown may be the most difficult aspect of many projects.
  • You might point out to students that there are those who claim that the real benefit of using project management tools comes from the planning and organizing effort, not the actual management of the tasks during the project.
  • As you discuss the various project scheduling techniques, you should include at least: - the basic assumptions of the technique - problems typically encountered in applying it - the nature of the effort required to keep the tool current - sources of problems - the nature of the decisions supported by the tool - the nature of the management effort and cost associated with using the tool.
  • What circumstances lead the two organizations to develop different, yet similar tools for the management of complex projects? In your discussion of PERT/CPM, you should probably note that PERT helps us identify critical tasks/activities and look at the probability of completing the project by a given date; CPM helps us analyze the cost/time tradeoffs possible if we need to speed the project up.
  • Students should be informed that an alternate representation where the node represents the activity, and the arrow the event are also used. The notation illustrated here comes from PERT; the alternate from CPM.
  • It should be noted here that a dummy activity is required because of the way in which PERT/CPM models are represented in the computer.
  • In your discussion of activity times, you should probably at least make note of the difference between “most likely” and “average” or “ expected” completion times.
  • This and the next several slides illustrate the definitions of terms appropriate to critical path analysis. There are many opportunities for good managers to truly manage a project once they have a PERT network established. For instance, sub-contractors know early start and late start times and the managers know the activities on the critical path upon which to focus effort.
  • This and the following slide illustrate the translation of Early and Late Start and Finish time to Gantt charts.
  • There are those that argue that the Polaris could not have been built without the use of project management techniques (PERT).
  • Another issue with respect to the use of PERT/CPM is the cost and amount of management time require to keep the system up to date.

  • Purposes of Project Scheduling♦ Shows the relationship of each activity to others and to the project as a whole♦ Identifies the precedence relationships among activities♦ Encourages the setting of realistic time and cost estimates for each activity♦ Helps make better use of people, money, and material resources by identifying critical bottlenecksPowerPoint 16-28 © 2001 by Prentice

  • PERT and CPM♦ Network techniques♦ Developed in 1950’s ♦ CPM by DuPont for chemical plants ♦ PERT by U.S. Navy for Polaris missile♦ Consider precedence relationships and interdependencies♦ Each uses a different estimate of activity timesPowerPoint 16-33 © 2001 by Prentice
  • Questions Which May Be Addressed by PERT & CPM ♦ Is the project on schedule, ahead of schedule, or behind schedule? ♦ Is the project over or under cost budget? ♦ Are there enough resources available to finish the project on time? ♦ If the project must be finished in less than the scheduled amount of time, what is the way to accomplish this at least cost? PowerPoint 16-34 © 2001 by Prentice
  • The Six Steps Common to PERT & CPM Define the project and all of its significant activities or tasks Develop relationships among the activities. (Decide which activities must precede and which must follow others.) Draw the network connecting all of the activities Assign time and cost estimates to each activity Compute the longest time path through the network. This is called the critical path Use the network to help plan, schedule, monitor, and control the projectPowerPoint 16-35 © 2001 by Prentice

  • Dummy Activities♦ Activities are defined by beginning & ending events ♦ Example: Activity 2-3♦ Every activity must have unique pair of beginning & ending events ♦ Otherwise, computer programs get confused♦ Dummy activities maintain precedence ♦ Consume no time or resourcesPowerPoint 16-40 © 2001 by Prentice

  • PERT Activity Times♦ 3 time estimates Optimistic times (a)  ♦ ♦ Most-likely time (m) ♦ Pessimistic time (b)♦ Follow beta distribution♦ Expected time: t = (a + 4m + b)/6♦ Variance of times: v = (b - a)2/6PowerPoint 16-42 © 2001 by Prentice
  • Critical Path Analysis♦ Provides activity information ♦ Earliest (ES) & latest (LS) start ♦ Earliest (EF) & latest (LF) finish ♦ Slack (S): Allowable delay♦ Identifies critical path ♦ Longest path in network ♦ Shortest time project can be completed ♦ Any delay on critical path activities delays project ♦ Critical path activities have 0 slackPowerPoint 16-43 © 2001 by Prentice
  • Earliest Start and Finish Steps♦ Begin at starting event and work forward♦ ES = 0 for starting activities ♦ ES is earliest start♦ EF = ES + Activity time ♦ EF is earliest finish♦ ES = Maximum EF of all predecessors for non- starting activitiesPowerPoint 16-44 © 2001 by Prentice
  • Latest Start and Finish Steps♦ Begin at ending event and work backward♦ LF = Maximum EF for ending activities ♦ LF is latest finish; EF is earliest finish♦ LS = LF - Activity time ♦ LS is latest start♦ LF = Minimum LS of all successors for non- ending activitiesPowerPoint 16-45 © 2001 by Prentice
