Most Likely Time when Expected Time is Known Solution

STEP 0: Pre-Calculation Summary
Formula Used
most_likely_time = (6*Mean time-Optimistic time-Pessimistic time)/4
tm = (6*te-t0-tp)/4
This formula uses 3 Variables
Variables Used
Mean time - Mean time, also called as expected time is the time needed to complete an activity. (Measured in Day)
Optimistic time - Optimistic time is the shortest possible time to complete the activity if all goes well. (Measured in Day)
Pessimistic time - Pessimistic time is the longest time that activity could take if everything is wrong. (Measured in Day)
STEP 1: Convert Input(s) to Base Unit
Mean time: 20 Day --> 1728000 Second (Check conversion here)
Optimistic time: 120 Day --> 10368000 Second (Check conversion here)
Pessimistic time: 365 Day --> 31536000 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
tm = (6*te-t0-tp)/4 --> (6*1728000-10368000-31536000)/4
Evaluating ... ...
tm = -7884000
STEP 3: Convert Result to Output's Unit
-7884000 Second -->-91.25 Day (Check conversion here)
FINAL ANSWER
-91.25 Day <-- Most likely time
(Calculation completed in 00.031 seconds)

What is PERT ?

Program Evaluation and Review Technique (PERT) is a method used to examine the tasks that are in a schedule and determine a variation of the Critical Path Method (CPM). It analyzes the time required to complete each task and its associated dependencies to determine the minimum time to complete a project. It estimates the shortest possible time each activity will take, the most likely length of time, and the longest time that might be taken if the activity takes longer than expected.

How to Calculate Most Likely Time when Expected Time is Known?

Most Likely Time when Expected Time is Known calculator uses most_likely_time = (6*Mean time-Optimistic time-Pessimistic time)/4 to calculate the Most likely time, The Most Likely Time when Expected Time is Known is based on experience and judgement based on time required if the activity is repeated number of times essentially under same situations. It reflects a situation " things are normal, nothing exciting.". Most likely time and is denoted by tm symbol.

How to calculate Most Likely Time when Expected Time is Known using this online calculator? To use this online calculator for Most Likely Time when Expected Time is Known, enter Mean time (te), Optimistic time (t0) and Pessimistic time (tp) and hit the calculate button. Here is how the Most Likely Time when Expected Time is Known calculation can be explained with given input values -> -91.25 = (6*1728000-10368000-31536000)/4.

FAQ

What is Most Likely Time when Expected Time is Known?
The Most Likely Time when Expected Time is Known is based on experience and judgement based on time required if the activity is repeated number of times essentially under same situations. It reflects a situation " things are normal, nothing exciting." and is represented as tm = (6*te-t0-tp)/4 or most_likely_time = (6*Mean time-Optimistic time-Pessimistic time)/4. Mean time, also called as expected time is the time needed to complete an activity, Optimistic time is the shortest possible time to complete the activity if all goes well and Pessimistic time is the longest time that activity could take if everything is wrong.
How to calculate Most Likely Time when Expected Time is Known?
The Most Likely Time when Expected Time is Known is based on experience and judgement based on time required if the activity is repeated number of times essentially under same situations. It reflects a situation " things are normal, nothing exciting." is calculated using most_likely_time = (6*Mean time-Optimistic time-Pessimistic time)/4. To calculate Most Likely Time when Expected Time is Known, you need Mean time (te), Optimistic time (t0) and Pessimistic time (tp). With our tool, you need to enter the respective value for Mean time, Optimistic time and Pessimistic time and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
