This NBC story on how mRNA vaccines might show promise in addressing pancreatic cancer was so good, our @ScienceDesk shared it twice. And we’re sharing it a third time because vaccines work, and mRNA vaccines are a phenomenal scientific achievement that should be celebrated […]

But also, it's a wonderful mix of backgrounds, experience, and *leadership*... So many ways people contribute and lead in settings like this. A question asked, enthusiasm and warmth conveyed, expertise and perspective shared,, so many ways that the culture and tenor of the group gets […]

He was so focused on feedback loops!
He introduced stock and flow diagrams, so feedback was a Big Idea for him.

“A feedback system, which is sometimes called a "closed" system, is influenced by its own past behavior. A feedback system has a closed loop structure that brings results from past action of the system back to control future action.”

“An open system does not observe and react to its own performance. An automobile is an open system which by itself is not governed by where it has gone in the past nor does it have a goal of where to go in the future. A watch, taken by itself, does not observe its own inaccuracy and adjust […]

“As used here a "system" means a grouping of parts that operate together for a common purpose.”
His use of “open” and “feedback” or “closed” systems is interesting…
“An open system is one characterized by outputs that respond to inputs but where the outputs are isolated from and have no […]

If you’re “ohhh, we need system understanding, and this needs to be highly dynamic and evolving as the ecologies of systems (co-)evolve” then you’re at or at least *so* close to “and this means we need to invest attention and expertise — we develop and sustain”

Starts in a week.
If you think that
• we need to pay attention to systems as systems we co-design as they co-evolve with contexts (of use, operation, development, organization, business, supply chains, …)
• this is what makes system and software architecture important actually AND it makes […]

I don’t know what I don’t know in someone else’s area of expertise, but I’m pretty confident that my “don’t know” area is much bigger than theirs — in ways that make a difference to outcomes.

Interesting histories, looking into examples of principles.
