CPI Stability Myth

As part of an on-going project to publish a history of EVM (target August 2022) I’m reviewing a lot of resources accumulated over a number of years. One of the first outputs is an update to our paper ‘The CPI Stability Myth’ – this review and update draws on a number of new resources to show where the research is applicable, where the 20% stability myth does not apply. Download from: https://mosaicprojects.com.au/Mag_Articles/N002_CPI_Stability_Myth.pdf

I have 2 projects open with 2 different data dates.

I have 2 projects open with 2 different data dates.  I am sliding a bar in the 2nd one but my Duration at completion is not coming out right - or to fix that the dates are not correct.  I have checked the calendars - could it be because of the data dates?  I don't see what that has to do with it but I don't know what else it could be.  I tried it actualized in the future and un-actualized.  mystery...it is not off by the difference in data dates....

Effect of a Crew on Productivity

Hello,

I've multiple crews working on the same activity type, but diferent buildings.

Assume the are steel fixers and the overall productivity is 100kg/day for today, and by simple analysis, I found that 50% of crews (Group A) produced 150kg/day and the other 50% of the crews (Group B) produced 50kg/day.

Is it correct to say that Group B reduced the overall productivity by 30% ?

What is the mathematical bases for such calculation? because I want to expand the analysis.

Thanks,

Ahmad.

% Complete Confusion - here is the data...

April 29 Data Date

April 29 Actual start on activity

Orig Dur = 20

Actual Dur = 5

Rem. Dur = 20

Per. Complete Type = Dur.

Dur. Complete = 0%

Sched. % Complete = 45% - how is this possible.

float -39.

Should I tell the contractor it has to be wrong to have used 5 days because the actual is on the data dates so cold not have used 5 days but a bigger question is how can the Sched % complete show 45% -seems high to me, I do not understand it.
