Mirrors, networks, and boundaries

Mirrors, networks, and boundaries

This time ten years ago, a movement was starting to coalesce to better align developers and operators. Looking back in the rear view mirror, we can say pretty clearly that movement was on to something.

DevOps has transformed how organisations use technology and organise people to deliver value to their customers faster and more safely.

But the landscape is changing. New challenges are coming into view, and leaders need to start preparing themselves for what comes next. What’s got us here won’t get us there.

In this talk we’ll look at what organisational psychology, product design, and anthropology have to say about what skills we need when navigating uncertainty.

  1. Mirrors, networks, and boundaries what technical leaders need to know

    for the next 10 years of devops Lindsay Holmwood
  2. Yes, but it’s not necessarily a bad thing. As long

    as the technology is an enabler of the underlying principles (communication, collaboration, a holistic view), the DevOps movement is still sound.
  3. "Organizations which design systems are constrained to produce designs which

    are copies of the communication structures of these organizations." – Melvin Conway
  4. “In a complex system, the technical architecture and the division

    of labor will “mirror” one another in the sense that the network structure of one will correspond to the structure of the other.”
  5. Creation of lateral relations: Direct contact Liaison roles Task forces

    Teams Integrating roles Managerial linking roles Matrix organisation

  9. – Sidney Dekker “multiple overlapping and partially contradictory descriptions of

    the same act are always possible, and even necessary, to approximate the complexity of reality”
  10. Keep in mind: * Subjective * Visibility informs priority *

    Maturity informs investment * Don’t replace arch diagrams * Maps change over time
  11. As the complexity of a system increases, the accuracy of

    any single agent's own model of that system decreases rapidly. Woods' Theorem
  12. • What are complex system • Simple, rugged, and dancing

    landscapes • The interesting in- between • Explore/exploit
