Kanban and Retrospectives

Following a couple of threads recently on the kanbandev Yahoo! group, I thought I’d try and put down my experiences and thoughts on the subject. In a timebox-based agile process, such as Scrum or XP, the retrospective typically happens at the end of the iteration, and is one of the items coupled to the iteration cadence.  Removing the iteration, and …

Estimation and Waste

There’s been some discussion recently on InfoQ and in the XP Yahoo! Group, as to whether estimation could or should be considered as waste.  My recent view has been that estimation is waste, but I think I am refining that position to be that “traditionally recognised” estimation is waste, and that there are subtleties which mean that some sort of …

Traffic Jams

One of the metaphors I use when I talk why a kanban system has work-in-progress (WIP) limits, is traffic jams. The greater the WIP, the lower the throughput, and this effect can be seen when too many cars clog up a motorway.

Agile 2008 – Wednesday

Wednesday kicked off for me with a talk by Ron Jeffries and Chet Hendrickson on “Natural Laws of Software Development” where they began with some basic ideas about delivering features and value early, and from that, derived most of the XP practices.  On the way they described some continuum, which struck me as good ways of thinking about approaches to …

Agile 2008 – Tuesday

This is a quick brain dump of the day for me – brief summaries and key highlights that stood out. The conference kicked off with an interesting keynote by James Suroweicki, author of Wisdom of the Crowds.  Essentiallly this is about how collective intelligence can be better than individual intelligence.  For example, we had a live experiment where all attendees …
