In today's competitive software landscape, aligning technical architecture with business goals is critical for achieving high performance. This talk explores how Domain-Driven Design (DDD) can be a powerful approach to optimize DORA metrics—Deployment Frequency, Lead Time for Changes, Change Failure Rate, and Mean Time to Restore. By focusing on business problems, fostering independent service paradigms, and organizing teams according to domain boundaries, DDD not only improves software design but also drives significant improvements in delivery efficiency and organizational agility. Attendees will gain insights into practical strategies for implementing DDD to achieve measurable outcomes in software delivery performance.
