Structure Eats Strategy

Many are familiar with Conway’s Law, which states that the architecture of a system reflects the communication structure of the organization that created it. If architecture mirrors the organizational structure, then having a solid structure is crucial, right? Jan Bosch explores this idea in his article "Structure Eats Strategy". He posits that many organizations prevent their growth due to ineffective organizational structures, communication, and distribution of responsibilities.

Bosch identifies four fundamental building blocks within any organization:
📍Business (B): Defines business strategy, revenue, and innovations.
📍Architecture (A): Establishes the technology stack and system structure.
📍Processes (P): Outlines activities and ways of working.
📍Organization (O): Defines departments, teams, and responsibilities.

Most organizations operate in an OPAB model (organization-first), meaning that the existing organizational structure dictates processes, leading to an accidental architecture shaped by the company's past.

Bosch argues that the BAPO model (business-first) is significantly more effective. This model begins with defining the business strategy, which shapes the architecture. The architecture then forms the processes and tools, and only after these elements are in place is the organizational structure defined.

The article offers a valuable framework for understanding the relationship between organizational structure and architecture. Structure should be a tool to help the business achieve its goals and guide architecture in the right direction for the future. Unfortunately, there are many examples where existing team boundaries lead to flawed architectural decisions. This results in support overheads, lower maintainability, reinvented wheels, and higher costs for the business.
