3. 3. INTRODUCTION <br />U.S. Navy&apos;s Polaris project<br />Critical Path Method (CPM) <br /> analysis technique used to predict total project duration<br />PERT is a Network Model Technique<br /> used to estimate project duration <br />Federal Urdu University of Arts, Science And Technology<br /> G-7/1,ISLAMABAD<br />

6. 6. Finding the Critical Path<br />Develop a good project network diagram<br />Add the Durations for all Activities<br />The dependant path is the critical path<br />Federal Urdu University of Arts, Science And Technology<br /> G-7/1,ISLAMABAD<br />
7. 7. Determining the Critical Path for Project X<br />
8. 8. BENEFITS OF PERT<br />Expected project completion time.<br />Probability of completion before a specified date.<br />The critical path activities that directly impact the completion time.<br />The activities that have slack time and that can lend resources to critical path activities.<br />Activities start and end dates <br />
9. 9. LIMITATIONS<br />Activity Time Estimation On Judgment<br />PERT Assumes a Beta Distribution <br />PERT Consistently Underestimates the <br /> Expected Project Completion Time<br />Federal Urdu University of Arts, Science And Technology<br /> G-7/1,ISLAMABAD<br />
