The Expected Time for an activity is its weighted average.

A calculate the scheduled completion time and identify the critical path 7 points

CPM was the discovery of M. Kelly of Remington Rand, circa The first test was made inwhen CPM was applied to the construction of a new chemical plant. In Marchthe method was applied to a maintenance shut-down at the Du Pont works in Louisville, Kentucky.

Unproductive time was reduced from to 93 hours. It proved to be a great communication medium by which thinkers and planners at one level could communicate their ideas, their doubts and fears to another level. Most important, it became a useful tool for evaluating the performance of individuals and teams.

How long will the entire project take to be completed? What are the risks involved? Which are the critical activities or tasks in the project which could delay the entire project if they were not completed on time?

Is the project on schedule, behind schedule or ahead of schedule? If the project has to be finished earlier than planned, what is the best way to do this at the least cost?


The procedure is listed below: The Project made up of several tasks should have only a single start activity and a single finish activity. Develop the relationships among the activities. Decide which activities must precede and which must follow others.

Draw the "Network" connecting all the activities. Each Activity should have unique event numbers.

Critical Path Analysis

Dummy arrows are used where required to avoid giving the same numbering to two activities. This is called the critical path. Use the Network to help plan, schedule, monitor and control the project. If these "critical" activities could be identified and assigned to responsible persons, management resources could be optimally used by concentrating on the few activities which determine the fate of the entire project.

Non-critical activities can be replanned, rescheduled and resources for them can be reallocated flexibly, without affecting the whole project. Five useful questions to ask when preparing an activity network are: Is this a Start Activity? Is this a Finish Activity?b.

Identify the Critical Path. (7 points) A-B-G-C is the Critical Path c. Fill in each ES, EF, LS, LF and Total Float on the second table for each Activity. It is important to identify project opportunities on the critical path in order to reduce the overall lead time.

Project opportunities in process areas not on the critical path will reduce the duration of the subprocess, but result in increased float time rather than impacting total lead time. Project Schedule Planning bpayne and Adrienne Watt.

sequence them in the right order, estimate the resources needed, and estimate the time it will take to complete the tasks. A critical path diagram is a useful tool for scheduling dependencies and controlling a project.

In order to identify the critical path, the length of time that. Help you to work out the critical path for a project where you must complete it by a particular date. When a project is under way, Gantt Charts help you to monitor whether the project is on schedule.

If it is not, it allows you to pinpoint the remedial action necessary to put it back on schedule. Work Breakdown Structure & Schedules T he WBS can be used to determine the critical path of the project and create the project schedule.

Remembrance Day (November 11) not included in schedule as it is a holiday. 4. Time allowed for glue and stain to dry. 5. Time allotted for shop closure due to Christmas holiday. Two network planning techniques are PERT and CPM. Pert uses probabilistic time estimates. CPM uses deterministic time estimates.

Pert and CPM determine the critical path of the project and the estimated completion time. On large projects, software programs are available to identify the critical path.
