Weekly - CW19 and CW20 – Zsolt Fabók

Weeklies will be bi-weeklies from now on, so here are the interesting things from the last two weeks - calendar week 19 and 20, 2011:

Let’s start with some games. The coin game and the lego game provide very good example and exercise about lean thinking, which is crucial for mastering Kanban
I found two screencasts about cycle times and SLA agreements. They are very good and give a good idea how to use cycle times and what kind of information can be extracted from them. They are available here and here
Pawel Prodzinski wrote a very nice article about Kanban systems and how they affect existing organisations

Jurgen Appelo shared yet another fascinating presentation about leadership: the purpose of leadership
I recently read Nick Oostvogels’ blog post about retrospective patterns, where he wrote about negativity during the retrospective. It is a very interesting topic, not just for Scrum or agile practitioners. I found a great post about how to handle negative people on zenhabits.net
Alistar Cockburn shared a video, which was made during one of his seminars. He talks about Shu-Ha-Ri, and he gave the best explanation on this topic I’ve ever seen, and defines what is the purpose of a real coach - help people to get to Ha state from Shu. The video is available here

I think everybody was in a situation where a problem arise and nobody really know why, and after spending a lot of effort on fixing it the root cause is still unknown. Well, Jeff Atwood got into a similar situation and you can read about his experience here
