Imagin the following situation: We have a Critical Chain lenght of 100 days We have a completion buffer of 50 days Tasks A, B, C are the last three tasks on...
If I understand your model correctly, Tasks D and E can almost be considered as "noise" in the system. A 45 day feeding buffer is not appropriate. Get better...
I scanned the archives and did not see this topic addressed: How are practitioners of CCPM calculating their task durations? Many suggest you get the 90%...
Dann, We use it in a rather subjective manner. First, every engineer is educated in Critical Chain theory, so they understand the intent of the '50% estimate'...
My first question to the list. I'm wondering what is the best way to reach project management professionals. What magazines do they/you read?? ? Ok, that's...
In my opinion this is not a question of "calculating" - it is a question of "cultur". If it is still a game, the cultur has not been changed. In my projects I...

As the objective is to estimate accurately the actual and possible length of the project AND at the same time to avoid wastes of time due to local time...
This kind of question always bothered our users too. It's the reason you are supposed to analyze your networks to look for just this kind of circumstances. I...
Based on the earlier comments that Uwe's problem may be software specific, what is the state of play with CCPM tools today? I have looked at CCPM-plus and have...
Hi there, I am doing a dissertation for my mba related to the critical chain concept. The subject that I am looking at is: Critical Chain and Project Risks...
You could try reading my dissertation here: http://www.clarkeching.com/2004/04/my_mba_disserta.html You could also check out Tom Demarco and Timothy Lister's...
Hi, I have started studying for my PMP certification. I have noticed that the Critical chain project management methodology is conspicous by its abscence in...
... There are many ways of estimating durations for CC schedules, some better than others. Your approach is reasonable, especially if you ask for the 90% ...
Hi! I usually try to avoid this topic, but I'd like to comment now. When someone says that "the flaws in cutting durations in half are much more serious than...
Hi all, I am managing the project management group for an IT shared services organization within a large enterprise. My next goal is improving our resource...
Mandar Critical Chain will be in chapter 6 of the PMBOK 2004 October edition. Why so long? Well it takes a while to get new ideas into the mainstream. Even so...
Hi, Folks Let me try to help you evaporate this cloud. I never speak of cutting durations. Nor do I speak of 'aggressive' durations, because I think it...
Hi, Rudigar Well, I hope so. They hosed it up in the draft. I sent them a correction, and they rejected it. We shall see. Larry Leach, PMP ... edition. ... ...
Interesting approach, Larry. Why not? I think the main point is that people have to realize they are part of the system, and their choices may not be the...
I think if you put the entire estimate in the buffer then you have lost individual accountability and the result may be a longer schedule, which is certainly...
Alice - ... I think the point is that individuals need to be accountable to the overall project (or portfolio). So Larry's idea, while definitely appearing...
Well said, Larry. I started the thread and just sat back and watched. It's been a very helpful conversation. I think your response sums up where I see us going...
Larry Leach says ... I think your overall process is very valid and I expect it is one that we will build our approach upon. However, I do wonder about the...
Dan, We only put 50% _of_the_critical_chain_ in the buffer. The safety from non-critical chain tasks (which are many) is not placed into the project buffer....
We in NUMA, a research institution, are doing a special research on project management tools of open source. Do anybody know some open source project ...
