CRITICAL PATH METHOD (CEE 320 – VDC SEMINAR) 4 February 2009 Jesse Santiago & Desirae Magallon Overview Background & History CPM Defined The CPM approach Definitions Class Exercise Background & History Developed in the 1950s by the US Navy Originally‚ the critical path method considered only logical dependencies between terminal elements Since then‚ it has been expanded to allow for the inclusion of resources related to each activity‚ through processes called activity-based resource

reduce the construction project completion time using the critical path method (CPM). In this method the longest path is the critical path which runs through one of the route in the project network diagram from start to finish. This project network diagram is illustrated on the printed assignment page‚ we have 10 tasks listed from A to J. Below is an activity list of the tasks; ACTIVITY | ACTIVITY DESCRIPTION | IMMEDIATE PREDECESSORS | ESTIMATED DURATION (WEEKS) | A | Clearing the vacant lot

Criticalchainprojectmanagement — Document Transcript • 1. Critical Path Method and Critical Chain Project ManagementProject schedule plan is the main plan included in any Project Management Plan. Project schedule isresponsible for bringing project time‚ cost and quality under control. Project schedule links resources‚tasks and time line together. Once a Project Manager has list of resources‚ work breakdown structure(WBS) and effort estimates‚ he is good to go for planning project schedule. Schedule

What is a critical path‚ and why is it important to project managers? How do you identify the critical path? What are some project reporting and communication techniques?

are linked with at least one predecessor and successor to have a proper sequence of work. This logical dependency between the tasks will determine afterwards the duration of the project. There are four types of dependencies which define the relation between pair tasks Finish-to-start (FS- the second task ‘successor’ can’t begin until the first ’predecessor’ is completed)‚ Finish-to-finish (FF- the completion of the successor depends on the completion of its predecessor)‚ Start-to-start (SS- the start
