We are the humans …

Significant innovation doesn’t happen until humans change their habits, or get out of the way …

Tenancy - where do we want to live?

you commune with the tree, but the forest is large

Where to put workloads and data

scale, complexity, knowledge

grow as flexible freedoms are thrust upon rigid systems by social or environmental forces

Going beyond “mere automation” …

Separation of concerns reduces complexity?

Delegation? Separation?

What allows us to handle complexity?

Weak coupling, and choice relationships

Atomize – keep it simple and light, autonomous

Untether – give me the freedom to work/live

Separation of concerns with

STRONG COUPLING

increases complexity!

Beware “orchestration”

Emergence - ecosystem

Don´t confuse tidiness with resilience

Don´t confuse untidiness with disorder

37

Complexity means cost

38

39

Balance exploration against targeted outcomes

Automate documentation of intent

Watch out for the human storyline

Delegate for tidiness with weak coupling
