Managing Project Processes

The Critical Path Method (CPM) is a vital project management technique used to enhance project efficiency through detailed analysis of interrelated activities. It helps identify the sequence of critical tasks that determine the total project duration. By estimating the duration of each activity and establishing their precedence relationships, CPM provides managers with insights into scheduling, resource allocation, and potential bottlenecks. Key terms include Activity, Path, Slack, and Earliest/Latest Start and Finish times. This method is essential for effective project control and timely completion.

  1. Managing ProjectProcesses

  2. Characteristics of a Project • A unique, one-time effort • Requires completion of a large number of interrelated activities • Resources, such as time and/or money, are limited • Typically has its own management structure

  3. Critical Path Method (CPM) • Designed to provide intense micro-control • System is dynamic; it continues to provide periodic reports as project progresses

  4. Manager’s View of CPM • List of project activities • Precedence relationship among activities • Estimate of each activity’s duration CPM processing procedures • Estimated duration of project • Identification of critical activities • Amount of slack for each activity

  5. d 6 3 b f h a 5 1 2 8 c g i 4 e 7 CPM Terminology • Activity • A task or certain amount of work required in the project • Requires time to complete • Represented by an arc (AOA) or a node (AON) • Dummy activity (AOA only) • Indicates only precedence relationships • Does not require any time of effort

  6. d 6 3 b f h a 5 1 2 8 c g i 4 e 7 CPM Terminology • Network • Shows sequential relationships among activities using nodes and arrows

  7. CPM Terminology • Path • Connected sequence of activities leading from starting event to ending event • Critical path • Longest path (time); determines project duration • Critical activities • All of the activities that make up critical path

  8. CPM Terminology • Earliest start (ES) • Earliest that an activity can begin; assumes all preceding activities have been completed • Earliest finish (EF) • ES + activity time • Latest finish (LF) • Latest that an activity can finish and not change project completion time • Latest start (LS) • LF - activity time

  9. Steps in CPM Analysis • Draw the CPM network • A graphic view of relationships among required activities • Path analysis • Determine length of each path (time required to complete each path) • Longest path is the critical path

  10. Steps in CPM Analysis • Network analysis • Working from left to right, find the EF and ES for each activity • Working from right to left, find LF and LS for each activity • Compute activity’s slack • Total Slack = LS - ES = LF - EF • This slack is shared with other activities • Free slack • Time an activity may be delayed without impacting the ES of successor activities
