Velocity (compared to speed or cadence) needs magnitude _and_ direction to define it. Running the wrong way fast doesn't make you #agile.

In 2020 I wrote 30 book summaries 📚

We tend to micro manage things we don’t understand. It makes us feel like we are in control even though we are not. Real control is creating a space to grow. It’s like a garden. You don’t make flowers grow, you give them water, sun, and good soil. It’s not chess, it’s farming.

"Agile" is now 20 years old.
"Devops" is 10.
The next wave has already started somewhere.
Thinking about developer onboarding for cloud platforms... would CDX work as a term, for cloud developer experience 🤔 My recent past has been all about ADP, application development productivity and application delivery platform.
On my way to the 2nd (annual I hope) #SquidConf in Stockholm, an unconference created by the participants. Learning to commute again. First time in 6 months. – at Stockholm, Sweden

If you think that agility is an "IT Project Managment" issue, you've already failed.
.@SpotifyCares , wouldn’t this be cool!? I know there are group sessions but this would be the next level. “Spotify’s next step to improve it’s streaming service…” by @austincondiff

You can work for years to be more Agile at the team level, and the first time a CEO says "I need a solid estimate and roadmap & schedule for developing this product," 100% of that agiity is flushed down the toilet. It has to come from the top down.

Why is continuous release (to customers) still controversial? The idea of a “release” was mandated by distribution issues (on floppy disks, for example 😀). It’s an obscolete concept. There is no reason a web-based app can’t release w/ every check in.

Definition of Done is a pretty common concept in Agile. Very useful. For Minecraft features we actually split it into four doneness levels. Designed, Runnable, Snapshotable, and Releasable. Design is emergent so it happens in parallell. We track this per feature & platform.

Qualities of a magnificent leader I see exemplified by this email:
1. Perpetual-learner
2. Desire for collaboration based on IDEAS, not status
3. Cites sources
4. Proud to mentor and be mentored
5. Seeks solutions, not credit for those solutions

13 years ago, I emailed Dr. Fauci out of the blue to ask if I might interview him for my undergrad thesis. He invited me to his office, where he answered all my questions. When I sent him the thesis, HE READ THE WHOLE THING (see his overly effusive review below). Who does that?!
