Beyond the Spotify Model: using team topologies for fast flow and organisation evolution
Key takeaways:
1. Why using the “Spotify Model” of team design is not enough
2. The four fundamental team topologies needed for modern software delivery
3. The three team interaction modes that enable fast flow and rapid learning
4. How to address Conway’s Law, cognitive load, and team evolution with Team Topologies
For effective, modern, cloud-connected software systems we need to organize our teams in certain ways. Taking account of Conway's Law, we look to match the team structures to the required software architecture, enabling or restricting communication and collaboration for the best outcomes.
This talk will cover the basics of organization design using Team Topologies, exploring a selection of key team types and how and when to use them in order to make the development and operation of your software systems as effective as possible. The talk is based on the forthcoming 2019 book Team Topologies and first-hand experience helping companies around the world with the design of their technology teams.
About Team Topologies
Team Topologies is a clear, easy-to-follow approach to modern software delivery with an emphasis on optimizing team interactions for flow. Four fundamental types of team - team topologies - and three core team interaction modes combine with awareness of Conway’s Law, team cognitive load, and responsive organization evolution to define a no-nonsense, team-friendly, humanistic approach to building and running software systems.
Devised by experienced IT consultants Matthew Skelton and Manuel Pais, the Team Topologies approach is informed by the well-known DevOps Team Topologies patterns (also authored and curated by Matthew and Manuel). Matthew and Manuel have worked with many organizations around the world to help them shape their teams for modern software delivery, and Team Topologies is the result of that experience.

Netflix:
“thanks for your insightful
articulations of devops
topologies. They inspired
many discussions and
helped us to think about
what model Netflix teams
could be/are using.”

Condé Nast International
“Your topological models
resonated extremely well
on both the Dev and Ops
side btw! I like the balanced
arguments, e.g. different
perspectives, for each
pattern.”

Team Interactions
3 defined Interaction Modes
Collaboration: 2 teams working together
X-as-a-Service: 1 provides, 1 consumes
Facilitating: 1 team helps another
65. 65
Sensing for Evolution
Not all teams in the org look the same
Discover, then push to Platform
Awkward team interactions are signals
Evolve the org with changing ecosystem
68. How well can the team as a unit “grok”
the systems they own and develop?
Push some things into a Platform?
Are skills or capabilities missing?
Explicit cognitive load

70. Are there major mismatches between
the team interactions and the required
software / system architecture?
What could be easily adjusted?
Large Conway mismatches

72. What would change if we adopted the
3 team interaction patterns?
Collaboration, X-as-a-Service, Facilitating
How would teams react & behave?
