At first when the bell goes the pairs are typically thinking only about finishing their current tweak. They are not thinking about getting to green. It is partly about reducing the average time to green, but mostly it is about controlling the average time to green. Of getting a sense of how far from green you are at any point in time. The aspects of TDD I hoped to convey using this exercise were not really the T in TDD but more the DD. The ongoing feedback nature of how tests can effect development. Hope this helps.Jon Jaggerhttps://www.blogger.com/profile/11560463167349216675noreply@blogger.comtag:blogger.com,1999:blog-6714530.post-11068888136746738632009-11-03T23:27:13.031+00:002009-11-03T23:27:13.031+00:00I don't really understand what they're sup...I don't really understand what they're supposed to learn from this game? Is my understanding correct, that they complete the same task every iteration and each computer has the same task? It seems like it's more about a teamwork exercise, to help the others out, since it's about reducing the average time, rather than learning anything about tdd... Obviously the time will go down each iteration, as they redo the same task... Am I misunderstanding something here?Jordan Soethttps://www.blogger.com/profile/11280721655392625890noreply@blogger.comtag:blogger.com,1999:blog-6714530.post-13935203704454912782009-08-17T12:53:31.628+00:002009-08-17T12:53:31.628+00:00This comment has been removed by a blog administrator.Itsolusenzhttps://www.blogger.com/profile/12017514819578661132noreply@blogger.comtag:blogger.com,1999:blog-6714530.post-61411905519130484982009-06-16T16:28:24.544+00:002009-06-16T16:28:24.544+00:00Hi Andy.

The first time to green was quite large (especially for such a simple exercise). About 6 minutes if I recall correctly. A long time when your sitting doing nothing. But we expected that. The second time to green was marginally quicker. People were still clinging to their existing habits. By the third iteration people had started to get it and were forming strategies. And, crucially, because we insisted on a change of iteration and machine each iteration the knowledge was making its way through the whole team. The exercise was deliberately trivial to try and leave as much spare capacity as possible for the main point of the game which was to learn about TDD.Jon Jaggerhttps://www.blogger.com/profile/11560463167349216675noreply@blogger.comtag:blogger.com,1999:blog-6714530.post-60825818895619985082009-06-16T12:57:17.753+00:002009-06-16T12:57:17.753+00:00It would be interesting to see the results and how...It would be interesting to see the results and how the participants improved as they figured out what was expected.Andy Murphyhttps://www.blogger.com/profile/01633654216050249341noreply@blogger.com
