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 …

Aspects of Kanban in Methods and Tools

I wrote an article on “Aspects of Kanban” which has just been published in the Summer 2010 issue of Methods and Tools magazine. Download it, have read, and let me know what you think! Alternatively, there is now an html version available.

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 …

As a result, we have put togther this small mini-conference to allow the speakers to share there ideas and experiences, and ensure that the time and effort put in to prepare …

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, …
