Hello, Matt. On Monday, December 31, 2007, at 8:05:35 PM, you ... Cycle time, as I understand it, is the time from beginning to end of a process. We would...
Ron Jeffries said on Monday, December 31, 2007 5:36 PM ... Whose productivity? A bit farther down in the thread you give several rather different spans,...
... Something just struck me about this. It isn't up to me to make those decisions. It is the team's. It is my job to provide the best guidance and advice I...
... Really? One team estimates in gummi bears and delivered forty gummi bears worth of stories; obviously, Team Gummi Bear has a velocity of 40. The other team...
Hi Ron, I some how seem to differ about these two teams and what they project about their velocities. Say we have a back log of Stories A through J (say 10...
Hello, John. On Tuesday, January 1, 2008, at 12:07:26 PM, you ... Yes, I agree with these observations. From a Lean viewpoint, I think that number 1 is more...
... You could use number of code-checkins/per week. If it's the team's job to change the codebase to add features, then code-checkins is a fairly direct ...
Hello, Edmund. On Tuesday, January 1, 2008, at 1:47:05 PM, you ... Of course not, but you changed the rules. And it seems to me this is begging the question....
... I think there's pretty good consensus that velocity is a rough measure, although people differ about the degree. Some people think that the measure is so ...
... Yes, but you don't implement an entire level at a time, but a series of end-to-end slices. ... Personally, I've stopped trying to write bottom-up layers in...
... Of course, it's a matter of degree and mind-set. People build working systems bottom-up all the time. My experience is that I usually spend too much time...
Hello, Sarath. On Tuesday, January 1, 2008, at 2:08:50 PM, you ... Yes, if we make the numbers different enough we can prove anything. Nonetheless, my point...
... Ok, makes sense. In this case, do you tend to use the mocks as scaffolding to be thrown away later, or do you keep the mocks around even after you've...
We have proposed a model integrating Software Reuse into the Extreme Programming methodology and are conducting a survey to obtain input into this idea. We...
Steve, If we believe Deming, the root cause of variations in output will be the system itself. Since the worker (developers in our case) don't have the power...
On Tuesday, January 01, 2008 2:06 PM ... It seems like there are two different ways of using a productivity measure. One is competitively, the other is as a...
... I definitely agree with the idea that improving methods should take precedence over setting numerical goals. On the other hand, I think numerical metrics...
... More than just input. Under agile, the team owns its process. The team responsible for modifying their process in response to feedback. This is the point...
... Once again, how do you measure individual velocity on a project where the team completes work? If Jim helps me complete a 2-point story, who gets credit...
... Personally, I muse over changes in velocity over time as a way to get insights into the estimation stability of a team. So, while I'll dabble with...
... I guess I missed the rule that says that two different teams will always have the same definition of what "one point" means. In fact, I was under the...
... I would think that increasing estimation accuracy would tend to only decrease the variance in velocity from iteration to iteration. My observation has been...
Hello, John. Well put. On Tuesday, January 1, 2008, at 6:52:06 PM, you ... Yes. It serves as a talking point, from which one can move on to what's really...
Hi Ron, ... I asked in an earlier post, and I'll repeat it here, where are you getting the notion that anyone wants to argue velocity out of existence? Some of...
... I find it hard to express what I want to express in a way that doesn't risk Vlad being upset with me, so I throw myself on your mercy and beg you to...
... Why do you believe you need to integrate software reuse into XP? I believe that software reuse is a natural consequence of effective design and collective...
... Can numbers be misleading? I thought only people could misinterpret them. Are you saying that there are people you generally don't trust to interpret the...
... I see: but velocity over time does indeed show "how we are doing" in the sense that it allows us to project when we are likely to finish the work we need...
... Oh, you mean "load factor". The cycle begins again. ... J. B. (Joe) Rainsberger :: http://www.jbrains.ca Your guide to software craftsmanship JUnit...
