Hi Kennet, that advice just does not seem logical to me, in the sense that who works in such isolation?!? Unless the experienced scheduler was recommending a very very detailed WBS that drills down to individual actions? I would never do that. There is one rule I mostly follow with multiple people working on a task; I never let MS project use the %s under Units, instead I enter in work per day per person manually under View / Details / Task Form, as appropriate, and I use fixed durations or fixed work tasks. I also don’t use automatic resource leveling on complex projects where I can’t easily see exactly what was leveled where (for simple projects it’s okay – I just don’t trust it, call me old fashioned). Hope that helps, and have fun scheduling!
