15. @stilkov Coming up with the “right” system boundaries is an

    architecture activity that must be done first

16. @stilkov Managing dependencies is the most important ongoing architecture task

17. @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?

27. @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

28. @stilkov If your goal is to support autonomous teams, architecture

    is an essential ingredient

29. @stilkov Size is the #1 enemy of agility. Keep your

    systems as small as you can.

30. @stilkov Extremely loose coupling requires very few rules, but they

    need to be enforced strictly

31. Pattern: Regulated Market @stilkov

35. @stilkov Not every person has to become a full-stack developer,

    but every team should be a full-stack team

36. Recommendations

37. @stilkov 1. Time to market requires supporting architecture

38. 2. Establish autonomous teams as key ingredient

39. @stilkov 3. Create evolvable structures
