Evaluating and planning architectural transformation
Improving maintainability and reducing risk in complex applications requires a systematic approach to architectural evolution. Applications with tangled dependencies and blurred responsibilities consume disproportionate maintenance effort. Feature additions that should take days stretch into weeks; bug fixes trigger unexpected, persistent failures; and developer onboarding becomes painfully slow. These symptoms don’t just reflect technical issues; they also have direct business impacts that need addressing.
Throughout previous chapters, we’ve seen how Clean Architecture naturally minimizes maintenance burdens through clear boundaries and explicit dependencies. Now, we can apply this same architectural lens to evaluate existing systems, identifying where violations occur and how to address them systematically. This doesn’t mean forcing an ideal Clean Architecture onto legacy systems all at once but, rather...
