All of this content used to be spread over three different blogs at three different domains and it's now been merged into one. Why was it ever three? Because at the time it seemed reasonable that each of them was for a different audiences, and yet over time I've found that the lines between topic areas got blurrier and tended to overlap. So now they're all together in one place.
If you encounter things that seem broken, let me know and I'll get them fixed.

There's a lot here and if you're not sure where to start, here are some popular starting points. From these, you'll find crosslinks to even more topics. Enjoy!
-
Neuroscience / Psychology
- Psychological Safety: An overview. For the science, see the SAFETY model. For Google's research into why it's important for high performing teams, see Project Aristotle. What happens when we don't have that safety?
- Anxiety and Stress: For the science, see Polyvagal Theory or a description of some neuroscience, illustrated with a bear encounter. To let go of that anxiety, see the Anti-Anxiety toolkit.
- Generally more about the brain: Cognitive bias, motivation, default mode network, systems 1 & 2 and neurotransmitters (chemicals) that drive behaviour.
- Language patterns: Why language is so important, and Clean Language, a specific language pattern that has excellent application for coaching.
-
How to improve...
- Meetings: The common problems with meetings. Improving the standup / daily coordination meeting. Retrospectives are covered in my popular video course Retrospective Magic. Then what if your people won't participate?
- Improving learning: with neuroscience and LEGO.
- Improvement: Continuous improvement in general. Understanding the metaphor of "lowering the water level".
-
Flow of value
- Metrics: Flow metrics, probabilistic forecasting.
- Waste: Overview of waste. Understanding the cost of interruptions, and the kinds of waste that gets in the way of flow.
- Work in progress (WIP): Setting initial WIP limits. What to do when we're overwhelmed with WIP
- Metrics and Forecasting: All of these have their own category now.
- Technical practices: Continuous integration, TDD as design, and ensemble programming.
- Ensuring we're building the right thing: Slicing stories and epics. Understanding the context of what we're building. Knowing how to prioritize that work.
- Something fun: The millennial whoop, and inattentional blindness.
- Recommended reading: I'm often asked for book recommendationsbook recommendations.
Moving backwards on a kanban board
A question we’re frequently asked is whether items are allowed to move backwards on a board. Many people will just say “no” but the real answer is more nuanced than that and depends on a number of factors.
Improving Predictability - All work must finish
In a previous post I introduced the four assumptions behind Little’s Law and the idea that they are critical to understanding and improving your system’s predictability. We’ve also already discussed the first assumption regarding the equality of average arrival and departure rates. If you haven’t read those previous posts I encourage you to go back to understand the background. As a reminder, the four assumptions are listed below.
Improving Predictability - Average Arrival and Departure Rates
In a previous post I introduced the four assumptions behind Little’s Law and the idea that they are critical to understanding and improving your system’s predictability. If you haven’t read that post I encourage you to go back to understand the background. As a reminder, the four assumptions are listed below.
Improving Predictability
Little’s Law is an equation that frequently appears in discussions of Kanban systems. While initially formulated as a part of queuing theory to describe the length of time people would spend in stores it has since been applied to many other contexts from manufacturing to knowledge work (particularly Kanban for the purposes of today’s conversation).
Getting Kanban metrics from the Jira API
If your team is using Jira then at some point you’re going to want to look at some flow metrics to see how you can improve. You’ll very quickly discover that Jira only provides two charts out of the box and that neither one is terribly useful. The cumulative flow chart has known bugs and the control chart is both difficult to read and has problems of it’s own.
The cost of interruptions and how to reduce it
Interruptions can be a significant source of waste. By their nature, interruptions cause a context switch as we lose track of what we had been working on to focus on the interruption. There is a significant cost to that context switch as it takes time and effort away from the task at hand. There is also a real impact on quality as mistakes are far more likely to happen when we’re distracted.
Massively overburdened with WIP
About once a year I run across a team that has at least ten times as many items on the board as there are people on the team. The worst I’ve ever seen was a team of ten people with 227 items in progress.
Flowing value
In Kanban we often talk about flowing value through the system and yet that’s somewhat misleading. The reality is that we can’t know whether a work item is valuable until we’ve actually finished the work and made it available to our customers.
Power of words
The words we use are far more important than most people realize. They have the ability to make deep changes in unconscious behaviour in ourselves and the people around us.
Pair Programming
Probably the most polarizing of all the Agile technical practices is pair programming. People either love it or hate it and often strongly hold one of those two positions even if they’ve never tried it for themselves.
