I'm wondering about where this method is being applied today. I'm also looking for areas where it was attempted but didn't work out.--- would love to hear those stories. Saving Changes...
Except for some Agile projects. We look at critical path, but rarely use the critical path method. According to Mike Cohn, he's never seen a team need a Gantt or PERT chart to figure out the critical path.

Mike and I must run in very different circles. I've never seen a team be able to calculate a Critical Path without PERT (meaning a task dependency network and task duration estimates.)

I am using it as a tool to manage Agile based initiative. It fits very well for that tipe of initiatives. Some people wrote "critcal path method" but I understood you are talking about Critical Chain which is Goldratt method.

Yes, Sergio. I also noted the apparent confusion between Critical Path and Critical Chain.
I view Critical Chain as an evolution based upon Critical Path, one which uses task estimate "safety" in a much more advantageous manner. And it's that technique that I'm asking about.
I see you are using Agile AND Critical Chain -- do you like how that's working out?
A major constraint (no pun intended) for its utilization is the unwillingness of leadership teams to change their mindset and behavior.
It is still a fringe approach which is likely why the volunteer committee who produced the PMBOK Sixth Edition elected to drop it from the Schedule Management knowledge area.

I will appreciate if anyone provides a name of a scheduling software utilizing the Critical Chain Method.
One not listed in this chart is Sciforma.com. I have experience with a few of these and am willing to share perspectives.

Just to add some information Critical Chain is based on Linear Programing that belongs to Operation Research field. Mr. Goldratt does not "invent" anything. The took those ideas that are outside there from 1800 mainly related to Theory of Restrictions and made them popular. I worked into an USA company and I took the courses with Mr Goldratt becasue at this time they was the only person able to teach the method. I was trained in my grade and posgrade career in the University on Linear Programing so it was very easy for me to apply the method. I made my own research (as part of the group I belonged in that USA company) to adapt the method to use with Agile methods. It was in 1995 but the trining I took was in 1989. So, if you take any software (there are free of use) that supports Linear Programing you can use it for any type of initiative. Then you can put it inside MS Project for example.

I would agree with that Rick. To calculate the CP, you need network diagrams which depends on task dependencies and estimates.
In agile, Ive seen many using the critical chain by introducing buffers especially in their initial estimates until they figure out the required velocity.
