Structure organizations modularly with loose coupling
Structure organizations modularly with loose coupling between components to contain failures and enable independent adaptation without cascading disruption.
Why This Is a Principle
Derives from Hierarchical Chunking Expands Capacity (hierarchically organized systems with stable subsystems evolve faster), Complex systems that work evolved from simple systems that (complex systems that work evolved from simple systems that worked), and Catastrophic failures in complex systems rarely result from (catastrophic failures result from alignment of multiple failures). Prescribes HOW to structure organizations - modularly with loose coupling - which is design guidance following from system robustness principles.
