Build for change
Evolutionary
Architecture pillars
Incremental
Evolutionary architectures are
built one part at a time, with
many different increments.
Speed to the next increment is
key.
Fitness function
Every system at different points
of their life need to optimise to
be "fit" for its environment.
Evolutionary architectures make
it explicit what "fit" means.
Multiple dimensions
Evolutionary Architectures must
support both *technical* and
*domain* changes

Adopt change end to end
Beyond the
architecture
Evolutionary mindset
Continuous Delivery
Trunk-based development
feature flags for faster
path to production
You build it, you run it
Teams own systems end to
end, from discovery to run
them at scale.
The right tool for the job
Clojure, Javascript, Python,
golang
Elasticsearch, PSQL,
DynamoDB, Neo4J
AWS, Terraform

A proactive
Technology team
Lead
Evolutionary Architecture is Signal AI way
Technology team to be ready for changes
Our ways of working is supporting and
enhancing this mindset
It’s about having a malleable system
Is the
secret sauce
of a fast
growing
business
And embrace change
