New Developments in Lean Software Development The book is out! <http://www.amazon.com/exec/obidos/ASIN/0321150783/poppendieckco-20> Lean Software Development:...
Congratulations Mary. Your draft opened up a whole new world for me (or, at least, it renewed my interest in Software Development). I will be ordering my...
I looked at your book in a bookstore and ordered it online. It should be here this week. I have read Critical Chain - what is your opinion of that book? Roger...
... Excellent article, Mary. I believe maturity on several levels is missing from our industry. The more I study the behaviour of companies, the more I have...
I have to agree with you on this too, Mary but this is a very tricky one. Take this quote about ISO 9000 certification (QCert) from a survey in TQM Magazine: ...
I like the Theory of Constraints very much, and I think Critical Chain is a good way to apply it to project management. To this I add a few qualifiers: 1....
Zeos was runner-up for the Malcolm Baldrige award. However, they went steadily downhill in the market and were soon acquired by Micron, who was competing...
... I was once part of an ISO 9001-certified software development company. The company went for the certification because one of its major customers was...
I've had quite a bit of success managing projects with a combination of Scrum, XP and Critical Chain. Yes, we do 50% estimates at the start of each project....
... Yeah, there is something very strange about human beings. I notice that with things like pair programming. All the evidence points to it producing much,...
Mike, I really like the 50% / 90% estimate approach. It certainly addresses a lot of problems - from penalizing good estimates to risk assessment to Critical...
Hi Pascal, ... My twisted mind says... I'll bet this dysfunction didn't start with the assessment. So maybe these assessments are valuable after all -- not as...
Hi David, ... What makes cheating an issue for you? How are you affected by cheating? Dale -- Dale Emery -- Consultant -- Resistance as a Resource Web:...
Thanks, Mary. I$B!G(Bve actually written quite a bit on estimating this way and why more conventional (padded) estimates and planning fail. If anyone is...
... Hi Dale, Perhaps cheating is a poor choice of word? Perhaps what I'm really asking is how do we ensure that we assess companies accurately? In Mary's...
Agile may discourage estimates beyond the current iteration, but it is fairly common practice in XP to have a 3-6 month backlog of estimated stories. There's...
You could start by giving the certificate an unattractive name, so there was no value in the certificate aside from its observed effects on the organization. ...
Here's my question about critical chain--they work very hard to time sequence a fixed set of tasks using a fixed set of resources with tough resource mapping...
I use Scrum plus as many XP practices as I can convince a team to adopt (usually most but pair programming is a tough sell!). Doing this we always estimate...
I think there is a difference between a rough estimate of duration of future work and an estimate detailed enough for Critical Chain to work. Of course...
Mary- Very true that the rough estimates of project duration I'm referring to can be way off. They are better than nothing and it scares me how many companies ...
Kent, Critical Chain only maps constraints. It is part of the Theory of Constraints (as you know) which seeks to eliminate constraints through elevation. In...
I think the key differences between XP style estimates and CC is that CC is trying Big Upfront Estimating in the absence of feedback... CC estimates 100 tasks...
I'm reading Lean Software Development now and it is very good. I am about to embark on a new project. Some of the project will be done offshore (in India) and...
Roger, I have talked to Matt Simons at ThoughtWorks about offshore development with agile processes, since he has done it successfully. He wrote an article...
This illustration is the up-front-designed buffer I'm talking about: tasks x,y,z followed by pre-determined buffer calculated from estimates of x, y, z. The...
If i understand what you're suggesting in the context of buffers, it's a way to compensate for those unknowns in the project. It's like a bank account with...
Outsourcing to low cost, high quality vendors seems to be a hot topic right now. This month's IEEE Software contains an article "An Eye on India: Outsourcing...
