API-First Transformation: From Tactical Decisions to Strategic Changes

This meetup explores how API-First thinking has become a foundational approach for system modernization and transformation, helping organizations expose capabilities, decouple systems, and accelerate digital initiatives.

While API-First has proven effective in many transformation efforts, real-world experience shows that APIs alone are not sufficient to address the deeper structural, behavioral, and organizational challenges embedded in legacy environments.

The session

• proposes a broader, more holistic modernization journey by complementing API-First with systems thinking, event discovery, and organizational alignment
• introduces how combining API-First with SEDA (Systemic Event Discovery Approach) offers a more practical and adaptive path—one that enables evolutionary change and supports asynchronous collaboration between organization and technology
