Failure Is Not An Option

Before reading this post, I encourage you to have a go at this quick puzzle to test your problem solving. Go on, you won’t regret it! How did you do? I’ve used this challenge numerous times in various talks and workshops and I find that the majority of people follow the same pattern. They only test their hypotheses by guessing …

Insights from a Kanban Board

I was working with a team this week, part of which involved reviewing their kanban board and discussing how it was evolving and what they were learning.

This post is a high level overview of the model I use when I think about Kanban Systems. As the saying goes, “all models are wrong, some are useful”. This is what I currently find useful based on working with teams and organisations in recent years. At the heart of the model is Systems Thinking. Without looking at what we …
