18-4Project Management Ability to motivate and direct team members. Make trade-off decisions. Expedite the work when necessary. Put out fires. Monitor time, budget, and technical details. Strong leadership skills. Function in an environment that is beset with uncertainties. Persuasion and cooperation of others to realize project goals. Maintain ethical behavior. Work with project champions, people, usually within the company, who promote and support the project. Project Management Skills
18-5Project Management Temptation to understate costs Withhold information Alter or mislead status reports Falsify records Compromise workers’ safety Approve substandard work Ethical Issues

18-11Project Management PERT and CPM PERT: Program Evaluation and Review Technique CPM: Critical Path Method Graphically displays project activities Estimates how long the project will take Indicates most critical activities Show where delays will not affect project

18-13Project Management Project Network – Activity on Node (AON) Locate facilities Order furniture Furniture setup Interview Remodel Move in 4 Hire and train 7S
18-14Project Management Project Network Path: A sequence of activities that leads from the starting node to the ending node. Critical path: The path with the longest activity time. Slack: The difference between the length of a given path and the length of the critical path.
18-15Project Management Network activities –ES: early start –EF: early finish –LS: late start –LF: late finish Used to determine –Expected project duration –Slack time –Critical path Project Network Time Estimation
18-16Project Management Project Network Time Estimation ES and EF Computation: –EF = ES+t –ES for activities leaving nodes with multiple entering arrows is equal to the largest EF of the entering arrow. LS and LF Computation: –LS = LF-t –For nodes with multiple leaving arrows, LF for arrows entering that node is equal to the smallest LS of the leaving arrow.
18-17Project Management Project Network Slack Time The slack time can be computed in either of two ways: Slack = LS - ES or LF – EF

18-23Project Management Time-Cost Trade-Offs: Crashing To avoid late penalties, To take advantage of monetary incentives for timely or early competition of a project, To free resources for use on other projects, To beat the competition to the market, or To reduce the indirect costs associated with running the project.

18-31Project Management Limitations of PERT Important activities may be omitted Precedence relationships may not be correct Estimates may include a fudge factor weeks
18-32Project Management Imposes a methodology Provides logical planning structure Enhances team communication Flag constraint violations Automatic report formats Multiple levels of reports Enables what-if scenarios Generates various chart types Advantages of PM Software
