Software architectural design can be integrated into software design evolution by following some best practices and principles, such as involving stakeholders in the process, using standards and guidelines, utilizing tools and frameworks, relying on patterns and best practices, and gathering feedback and metrics. Stakeholders should provide feedback, suggestions, and validation throughout the software architectural design process. Established and recognized standards and guidelines for software architecture, such as ISO/IEC/IEEE 42010, should be used to ensure the quality, consistency, and compatibility of the software architecture. Appropriate and effective tools and frameworks for software architecture, such as UML, ArchiMate, or ADLs, should be employed to support the creation, documentation, evaluation, and evolution of the software architecture. Reusable patterns and best practices for software architecture, such as GRASP, SOLID, or DDD should be utilized to enhance the design and implementation of the software architecture. Finally, feedback and metrics for software architecture such as ATAM, SAAM or QAW should be gathered to measure and improve the quality and performance of the software architecture.
