Well I used to estimate in several IT projects
- level of effort for the project manager (1 FTE for the duration of the project)
- apportioned efforts for the quality manager (QA), at e.g. 10% of
- discrete effort following the WBS structure for project work Saving Changes...
Thomas, thank you so much for pointing out real example, you actually made it more clear Saving Changes...

A level of effort estimate is your second estimate, after your rough order of magnitude estimate. While the ROM is often +/-50%, the LOE should cut it in half. Saving Changes...
Stéphane , Thanks for your reply so as we know that LOE doesn't produce deliverable and the cost variance can fit into that as you mentioned some consider ROM as 30- 70 % or 20 - 80 % You take it as 50% - + so are you referring to the definitive estimate as LOE.
What about the discrete efforts is that related to CPM and all WBS. Saving Changes...

By definition, discrete means a single, small unit. I would take discrete effort to be the lowest amount of effort recorded against an activity.

Riyadh,
I would suggest that this is all dependent on what and who you are delivering to (ie the end user). I have found through experience that the effort is ever changing and must be adjusted through the project life. It is all well and good looking at the definitions but these are not set in stone.
The project manager AND his stakeholders must ensure what is progressed and when and how much effort to meet the requirements and scope. Saving Changes...
