## What is the expected time in Pert?

in Program Evaluation And Review Technique (PERT), a weighted average time that is widely used in a real life application of PERT to a complex project, where the completion times for activities are not certain..

## What is 3pt analysis?

Three point estimating is a technique which utilizes an optimistic and pessimistic estimate to determine the ideal estimate value for a project task. … It allows known risks to be quantified and built in to the project budget.

## What if there are two critical paths?

You can have more than one critical path in a project, so that several paths run concurrently. This can be the result of multiple dependencies between tasks, or separate sequences that run for the same duration. … In fact, the activities on the critical path are not always the most important parts of the project.

## What is a most likely time?

Most likely time(tm) – It is the estimate of the normal time the activity would take. This assumes normal delays. If a graph is plotted in the time of completion and the frequency of completion in that time period, then most likely time will represent the highest frequency of occurrence.

## How do you calculate optimistic time?

The PERT estimate (E) is based on a formula that includes your optimistic time estimate (O), your most likely time estimate (M) and your pessimistic time estimate (P). The basic equation is this: E = (O + 4M +P) / 6 .

## What is a PERT diagram?

A PERT chart is a visual project management tool used to map out and track the tasks and timelines. The name PERT is an acronym for Project (or Program) Evaluation and Review Technique.

## What is critical path example?

For example, in the diagram below, activities E, F, G, H, and I make up the critical path. Their total duration is 100 hours. Activities B, C, D and E make up the second longest sequence with a total duration of 90 hours. The difference between their total duration is 10 hours.

## What is critical path in PM?

In a project, the critical path is the longest distance between the start and the finish, including all the tasks and their duration. … To find this, project managers use the CPM algorithm to find the least amount of time necessary to complete each task with the least amount of slack.

## What is meant by crashing?

Crashing is the technique to use when fast tracking has not saved enough time on the schedule. It is a technique in which resources are added to the project for the least cost possible.

## What is difference between PERT and CPM?

PERT is that technique of project management which is used to manage uncertain (i.e., time is not known) activities of any project. … CPM is that technique of project management which is used to manage only certain (i.e., time is known) activities of any project.

## What is critical path calculation?

Critical Path: The continuous string(s) of critical activities in the schedule between the Start and Finish of the project. The sum of the activity durations in the Critical Path is equal to the Project’s Duration; therefore, a delay to any Critical Activity will result in a delay to the Project Completion Date.

## Is Critical Path the longest path?

In project management, a critical path is the sequence of project network activities which add up to the longest overall duration, regardless if that longest duration has float or not. This determines the shortest time possible to complete the project. There can be ‘total float’ (unused time) within the critical path.

## What is most likely time in project management?

Most likely time, expressed as ‘tm’, represents estimate of time for completion of an activity, which is neither optimistic nor pessimistic, assuming that things should go in a normal way, and if the activity is repeated several times, in most of the cases, it will be completed in time represented by t.

## What is optimistic and pessimistic time?

The optimistic time is the fastest possible time needed to complete the task and usually involves additional cost. Normal time is the most likely time, while the pessimistic time is the slowest time needed to complete the task.

## What is pert formula?

PERT calculates a weighted average as the PERT estimate by using the formula : Pert Estimate = (Optimistic + (4 X Most Likely) + Pessimistic)/6.
