Thanx Richard for the reply. I have few more queries. Selling the CCPM concept looks relatively simple for me coz of the logical explanation of cutting the...
I can only echo and commend Richard Zultner's advice on de- emphasising the importance of buffer size calculations. In a single- project CC undertaking last...
Kala Could you please provide more information on the type of software projects which you are dealing with? Also could you explain who has initiated the ...
Hi Kala You might find the following basic steps of interest: There are several challenges in implementation: * Getting people to single tasking * Getting...

Kala: I notice you are a CMM Level 5 organization. So a couple of caveats to what has been said so far. a. If you are CMM 5 then you should have a substantial...
Hi, Doug Good to see you are still here! Just a word of caution to "Level 5" organizations. It may mean you have institutionalized dysfunctional behaviors. You...
Hi Larry Glad to see you here again. I was wondering about the suggestion that having historical data might help the organisation to better plan its projects....

Hey Larry and Jim, Good to see you posting again. And you bring up some interesting points. I get a newsletter from construction industry peer Michael Stone....
Peter, Don't you think most construction companies use use the bidding process to select the subcontractors, who in turn create the estimates. Poor estimators...
Hi Again, Peter OOPs, I might have sent my reply before I was finished. Oh, well. BTW, we FINALLY poured the footings for the new digs yesterday! Hope to be in...
Karl, Yes, General Contractors (GC's)often use the bidding process to select their subs, but the subs must then use their own data (in the form of past...
Hi, Peter Well, I guess I somehow blew off my reply to this. I will try again. I do not know what the author means by "error factor", but I fear from the way...
Hi Larry, Peter et al. To dig deeper on this, we would need to enter the realm of cost allocation practices. Perhaps that needs another thread? I think you...
Jim, From my own personal experience, this was the MOST difficult hurdle in my coming to terms with CC. A blanket statement that asks for a 50% reduction in...
Actually the FFP contract is one of the prime examples of CCPM at work. What you need to do is approach this sub-contractor in exactly the same way Goldratt (I...
Doug, I can think of several ways to earn an early finish incentive on a project. 1. More effort, or increased efficiencies, by the allocated resources. 2....
Richard, Looking back on the history of this forum, the "Buffer Sizing" topic seems to get the most discussion. I'd like to extend my waste management thinking...
Hi, Jim I recommend using the EC on this. I find it more useful than the NBR when developing new solutions, because it encourages examining assumptions in...
Peter: I think we agree. In a FFP mode I don't care how you achieve the incentive for timely, quality delivery. That in fact is why you are a successful ...

All, Here is empirical data from a given set of tasks. How would you construct a CC estimate given this history? Note: The standard construction industry...

Sorry for the formatting on my last post. I've attached an Excel Buffer Sizing Worksheet to the Files section. In it, I have proposed four methods to estimate...
Larry suggested I join and tell how I've been using CC in teaching sailing on San Francisco Bay the last several years. Weekends, I work for Club Nautique,...
Hi, Oliver Welcome, and thanks for an excellent explanation of a process to reduce variation in the difference between estimated time and actual time(s). Does...
Larry, From a business standpoint: is the goal to reduce variation, or to meet or exceed the profit goal? In Oliver's story, he adjusts the speed of the boat,...
