The best engineering teams do not build systems that are merely “scalable.” They build systems that remain understandable, replaceable, testable, and safe to modify as the product, team, and business evolve. This article explores a practical engineering discipline for designing software around change: isolating unstable decisions, creating intentional boundaries, treating observability as part of architecture, and reducing the social cost of modification.
