The silent killer of high-performance teams is overburden (Muri).
In the final part of my blog series on Lean Software Delivery, I look beyond the symptoms to expose the source and set out a practical sociotechnical plan to solve it.

Ever feel like your delivery is a constant cycle of "hurry up and wait"? That’s Mura (unevenness). It is the root cause of the waste (Muda) we see in software development. Inconsistency makes delivery unpredictable and unsustainable. It’s time to look at the source. 🧵

We obsess over 'velocity' but rarely talk about the silent killer of momentum: Waste.
In manufacturing, waste is physical scrap. In software, it’s invisible friction. "Busy" does not mean effective. To go faster, we need to stop looking at what to do, and start looking at what to stop. 🧵

Your "Agile" process is probably why your delivery feels chaotic.
Unevenness in how work flows is Mura, and it’s the real source of waste. Part 2 of my blog series breaks down how to measure this and how to actually fix it.

Fourth weight loss goal hit: down 18 kg in 32 weeks. My fifth goal takes me into my healthy weight range, then the final one to my target weight. I should get to 3 stone total loss (19.1 kg) in the next couple of weeks.
