The ‘What’ of Scientific Development

The key is that our hypotheses are not deliverables. They are ideas seeking validation. This twist has important ramifications for how we end and enter sprints. At the end of a sprint, we can look at what we’ve done and for each hypothesis we can say: “yes” or “no”. Our planning is about what we

The ‘Why’ of Scientific Development

Can we use our backlog for professional growth by tracking and talking about what we want to learn? Stories are nice, but… As an agile coach I’ve spent a lot of time teaching and helping people practice writing stories in the classic format “As a […] I Want […] So That […]”. The virtues of this

Jidoka and Captured Knowledge

In manufacturing, you likely know the problems to look for; broken threads, misshapen parts, etc.. In software, you may have no idea what kinds of problems you may create by changing code. In this way, practicing jidoka is invaluable. It’s how later developers know what can break, what is broken, and offers wisdom about how

Jidoka (automation with a human touch)

The two pillars of lean are just-in-time, and jidoka. Today we’ll look for jidoka in software development. What is jidoka Often translated as “automation with a human touch”, some people also use the word autonomation. The principle is rather simple. When designing a process, find opportunities for the process to self identify errors and stop

Muri, Kaizen & Retros

When do you most need a retro? When you feel as though you don’t have the time for it. Muri In lean, the feeling of stress (or the impossibility of your task) is called “Muri”. It should serve as a powerful indicator that something is terribly wrong. If you feel this as a member of

Takt Time & Waste Elimination

How does the use of sprints (takt) eliminate waste? By reducing Mura & Muri. Mura – Variability Imagine a lean auto plant with a 60 second takt. Expectations for everyone are clear. You will be done in 60 seconds. If you cannot consistently do your job in less than that, there is a problem. In

Takt Time & Sprints

Takt is a German word that has been adopted by lean. The original meeting is “beat” or “rhythm”. In an auto plant we may see a one minute takt. This means that every minute a finished car rolls off the assembly line, a dashboard is installed, a car is painted, etc.. Software development cannot possibly
