The Science of Lean Software and DevOps: Building and Scaling High Performing Technology Organizations

Forsgren PhD, Jez Humble, Gene Kim

This connection between communication bandwidth and systems architecture was first discussed by Melvin Conway, who said, “organizations which design systems . . . are constrained to produce designs which are copies of the communication structures of these organizations” (Conway 1968). Our research lends support to what is sometimes called the “inverse Conway Maneuver,” 2 which states that organizations should evolve their team and organizational structure to achieve the desired architecture. The goal is for your architecture to support the ability of teams to get their work done—from design through to deployment—without requiring high-bandwidth communication between teams. Architectural approaches that enable this strategy include the use of bounded contexts and APIs as a way to decouple large domains into smaller, more loosely coupled units, and the use of test doubles and virtualization as a way to test services or components in isolation.
