@stilkov Coming up with the “right” system boundaries is an
architecture activity that must be done first
@stilkov Managing dependencies is the most important ongoing architecture task
@stilkov You cannot decide to not have an architecture; if
you don’t actively create it, be prepared to deal with the one that emerges

Architecture?
@stilkov Conway’s Law: Organization → Architecture “Organizations which design systems
are constrained to produce systems which are copies of the communication structures of these organizations.” – M.E. Conway
@stilkov If your goal is to support autonomous teams, architecture
is an essential ingredient
@stilkov Size is the #1 enemy of agility. Keep your
systems as small as you can.
@stilkov Extremely loose coupling requires very few rules, but they
need to be enforced strictly
Pattern: Regulated Market @stilkov
Modularization Autonomy End-to-end responsibility
@stilkov Pattern: Autonomous Cells Stakeholder Stakeholder Stakeholder Biz Dev Ops

@stilkov Not every person has to become a full-stack developer,
but every team should be a full-stack team
Recommendations
@stilkov 1. Time to market requires supporting architecture
2. Establish autonomous teams as key ingredient
@stilkov 3. Create evolvable structures
