KEY TAKEAWAYS

CHAPTER 1

• Conway’s law suggests major gains from designing software architectures and team interactions together, since they are similar forces.
• Team Topologies clarifies team purpose and responsibilities, increasing the effectiveness of their interrelationships.
• Team Topologies takes a humanistic approach to building software systems while setting up organizations for strategic adaptability.

CHAPTER 2

• Organizations are constrained to produce designs that reflect communication paths.
• The design of the organization constrains the “solution search space,” limiting possible software designs.
• Requiring everyone to communicate with everyone else is a recipe for a mess.
• Choose software architectures that encourage team-scoped flow.
• Limiting communication paths to well-defined team interactions produces modular, decoupled systems.

CHAPTER 3

• The team is the most effective means of software delivery, not individuals.
• Limit the size of multi-team groupings within the organization based on Dunbar’s number.
• Restrict team responsibilities to match the maximum team cognitive load.
• Establish clear boundaries of responsibility for teams.
• Change the team working environment to help teams succeed.
