An architectural paradigm that shapes systems to evolve incrementally and in a controlled manner over time.
Evolutionary Architecture is a paradigm that enables software systems to evolve incrementally while preserving key architectural characteristics. It relies on fitness functions, incremental change, and automated validation to guide architectural evolution. The approach balances flexibility with long-term maintainability across teams and domains.
Aggregate value of defined fitness functions to rate architecture quality.
Time from requirement to delivered change as an indicator of evolvability.
Frequency of releases, showing how rapidly changes reach production.
Stepwise extraction of functions into separate, tested services using fitness functions.
Automated checks ensure compatibility under rapidly changing requirements.
Introduction of validation rules that control changes for conformity.
Define strategic goals and quality attributes
Derive and prioritize fitness functions
Integrate automated checks into CI
Plan and roll out incremental architectural changes
Establish continuous monitoring and adjustment
