Agile2010 Bag Packing with Kanban

At Agile2010, as at Agile2009, I went along to help the volunteer bag packing, and use it as an exercise in experimenting with Lean and Kanban ideas. Once again it was a huge success. We completed packing all the bags in (anecdotally) record time, and had great fun in the process. The video above was put together by Luiz Parzianello …

A Pattern for Using Scrum and Kanban

I’ve noticed a pattern that I’ve found myself using recently when I’ve worked with new teams that makes use of both Scrum and Kanban ideas. I’ve already said that I believe the two are complimentary, and this should help show how. I’ll often begin with a “Canonical Scrum” implementation. This gives a relatively simple introduction due to the ubiquitous language, …

The Flow Experiment

I put together a small simulation for the SPA Conference this year which seemed to go well, and which I re-ran at the London Limited WIP Society, and hope to run again. You can download the materials, and this is a short write-up of how it works so people can run it and experiment with it themselves. Overview The basic …

Does A Kanban System Eschew Estimation?

I was recently involved in a brief twitter conversation which started when Mike Sutton tweeted: estimation is not about the number that pops out. It is about exploring effort and discovering that you don’t know stuff. Paul Dyson responded: spot on! This is fundamentally what I don’t like about the kanban “if people find estimation hard, don’t make them do …

Kanban and Scrum – Intention and Implementation

In my last post I introduced the idea of a PVC System – one which exemplifies Pull, Value and Capability – and closed by posing the question as to whether Scrum could be considered to be a PVC System. In answering that question myself, I realised that there is another distinction which I will describe in this post. In doing …

From KFC Development to PVC Systems

I’ve been revisiting my earlier KFC Development work in light of my more recent focus on five primary practices. This is an brief overview of what’s changed, and what my mental model looks like now. Firstly, I’ve stopped referring to the practices as such, in favour of calling them aspects. Practices always felt slightly wrong, but at the time I …

A Kanban Multiverse – not from LeanSSC Atlanta

I should have been at the LeanSSC Conference in Atlanta this week, but unfortunately Eyjafjallajokull intervened. This is the Prezi I was going to use. It may not make much sense on its own but hopefully gives a flavour of what sort of things I was going to talk about. I’m hoping to put together a post together to flesh …

Defining the Last Responsible Moment

I was involved in a recent twitter discussion with Chris Matts about Lean’s “Last Responsible Moment”, and he set a challenge to come up with a usable definition. Chris’s opinion is that there isn’t one, compared to the Real Options equivalent. This then, is my response to that challenge. I will define the Last Responsible Moment (LRM) in terms of …

Facilitating A Kanban Konversation

As I mentioned in my Scrum Gathering Musings, I came up with a twist on the Goldfish Bowl format which I used during the Kanban Exploration Deep Dive.  Here are some more details. The Goldfish Bowl format works really well for facilitating a focussed discussion with a large number of people. It keeps the active voices to a manageable number, …

Systems Thinking, The Vanguard Method and Software Development

I’ve recently read John Seddon’s “Freedom from Command and Control“, which introduces his approach to Systems Thinking – the Vanguard Method. A few key points really struck home with me and helped clarify my thoughts on some of the challenges I’ve come across recently. First is the following simple diagram, which shows that Management is responsible for defining the System, …
