Alan, My experience has actually been the opposite to your description ;-) I've found many Scrum teams are more focussed on the process than on the team...they...
Rob: thanks. I think this may be an orthogonal issue to what I am looking for. Or too subtle a one. The Kanban teams I have seen get very concerned about how...
I recently read a blog post by Mark Graban<http://www.leanblog.org/2009/08/two-types-of-cycle-time-confusing.html>titled "Two Types of Cycle Time". In the...
Here are definitions from Lean Thinking by Womack. I figure this is a good place to start. Using an established common language can only promote understanding....
I like the distinction of development cycle time and lead time. From a customer perspective I typically include wait time within the development team in...
It think if you're an IT shop and can continuously deploy, you care about lead time. If your a shrinkwrap shop, ship a CD, download a .exe file, etc, and want...
In Steve McConnel's Code Complete 2nd Edition, page 29 & 30 (and probably others), he talks about the cost of finding defects in a software system... how much...
Pretty consistent with what I wrote in this message: http://finance.groups.yahoo.com/group/kanbandev/message/5337 That is: Lead time = for any process: the...
... I know of /no/ studies that /ever/ looked at this problem with construct validity. ( Ref: http://www.kaner.com/pdfs/metrics2004.pdf ) Most of the original...
... i certainly won't argue with that. so, assuming that the numbers are even relatively good... :) ... good questions. if we build on top of broken or...
Hypothesis: 1) The cost of finding defects have a non-linear relation to time 2) This cost is related to the lenght of the feedback loop. Shorter feedback...
Emil: I agree with the hypothesis. But I respectfully disagree with the Kanban does not prescribe short feedback loops. Kanban is based on shortening cycle...
Cost of finding a defect should decrease with shorter testing feedback loops Kanban does not prescribe testing at all. Thus should not affect this cost. The...
Great I have learned something today then! Kanban with K means more than I knew. Have you also abolished the thought that Kanban is not a process? Should I get...
Kanban certainly helps because it drives down lead-times, which means bug-fixes can be turned around quickly. If users know that after they report a defect it...
Posit: Fixing bug as you go, instead of batching them, improves the overall economy. KanBan can help with this in that it encourages individual assignments ...
I think you're right about large batches vs fixing as you go. I have to say I wish you wouldn't capitalise the B. The world and his trousers spell it with a...
Didn't Ohno say that you shouldn't codify process? (will check tomorrow, anyone got the book in reach?) Isn't that exactly what we are doing? Do we not risk...
In lean process is extremely codified and extremely changeable. Ohno says if you are doing the same process 30 days from now management is not doing their...
Taiichi Ohno asserted that method must not be codified. He claimed improvement is never-ending – and by writing it down, the process becomes crystallized. He...
yep From my point of view it sometimes looks like we are codifying the workflow signaling tool kanban into Kanban which prescribes other software-dev...
What Ohno meant with that is wise though. Kanban helps us see and do a lot of great stuff but in my opinion those things should not be codified into a Kanban...
<I-Think> The tools for understanding are going to be pretty common. Identify/Subordinate/Elevate the Constraint, Identify/Eliminate the Waste, Manage Risk,...
I've set up a kanban for an authoring process where we've mapped our stages in the workflow on a white board. One stage is clearly our bottleneck becomes items...
... I think you nailed it, Dean. I re-read some of the definitions from this thread and the previous one, and some of the source material today. it turns out...
Hi Dennis, ... I agree with this but still struggle with how to make the lead time indicator useful. Let's say that I get a feature request from Marketing via...
I don't have any clear answer, but maybe you can find some valuable ideas along these lines: - "Nine women don't make a baby in one month": authoring may be...
All, Due to an increasing number of requests I'm putting out a call for people to submit papers to be put into a Lean & Kanban booklet that will be available...
