How does P3 caculate project progress?

Dear Eddy,



Check in Tools -> options -> Summarization



here click duration .



Explanation for schedule report percentage complete:

----------------------------------------------------



Also in the schedule report the percentage is calculated based on the duration weight age of each activity.



For example

ID Du Early Start Early Finish

A 3 1-Dec-09 3-Dec-09

B 1 3-Dec-09 3-Dec-09



Now if your data date is 2-Dec-09



After summarization you get in the activity column area the percentage complete shows as

((Original Duration-Remaining Duration)/Original Duration) * 100

i.e,

((3-2)/3)*100=33.33%



in Schedule report it is calculated as follows,



Overall duration = 4 i.e,(3+1)

Now the weight age for Activity A is (3/4) = 75 %

and the weightage for Activity B is (1/4) = 25 %



As per date date if the percentage complete of activity A is 33% then in the schedule report you get only 24.75 %.



It is calculated by formula

(Activity % Complete * Weightage)/100

Activity A percentage complete is 33

Weightage is 75

i.e ( 33 * 75 )/100 = 24.75%

HI barry



you set baseline as a target for cross checking planned percentage completion and actual percentage and variance between them



you can check out in tabular report for values you require for s curve



Method of measurement depends on us ,how we use matters

P3 does not calculate progress on the bases of duration, rather it does it on the bases of Manhours allotted to each activity.



all it does after you add the total BOQ manhours , it creates an S-Curve and this is done by dividing the activity into days, thus manhours are also divided into days.

e.g you have an activity for 5 days and total manhours for this activity are 75, so P3 will divide these 75 manhours in five units of 15 Manhours each and put them in each slot (day). Now when you update your plan or insert achieved manhours. Let’s say you entered 60 manhours after 5 days. It will calculate the progress to be 80%. Because the work is only 80% complete irrespective of the time taken by u to complete the activity.



The same formula and technique is applied to the entire project and calculations.



You can even do it on paper but P3 does it for you.



If anyone thinks i am wrong kindly correct.



Cheers.

Check this formula



Percent of completion =[actual duration/total duration]*100



total duration = original duration + remaining duration



Actual duration =[Actual start-data date]-resource lag which is generally equal to zero

% of completion = {[original duration-remaining duration]/original duration}*100
