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, please 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!

The millennial whoop and our brain as a prediction engine

Understanding waste in the system

In Kanban, we are always trying to optimize for efficiency, effectiveness and predictability. Waste in the system is something that hurts all three of these objectives and is something we want to remove or reduce wherever possible.

The only way to win is to learn faster

Over the past 15 years of working with various agile techniques, practices, frameworks, and strategies I’ve found that there is one thread that ties them all together. They are all focused on improving our ability to learn and to apply that learning to our future work.

Determining cycle time from an online system

This post is aimed at a fairly niche audience so if you aren’t trying to make sense of poor data out of some ticketing system then you might want to skip this one.

Improving the daily coordination meeting

Just about all agile methods have some kind of a daily coordination meeting. It might be called a standup or a daily coordination meeting or a daily scrum or any number of other things. The point is that this meeting is focused on actively managing the work and it’s frequently done poorly.

Setting initial WIP limits

When starting a team up with Kanban, one of the earliest questions is how to you set initial WIP limits. The simple rules we use are covered in this video.
