Sustainability in Enterprise Architecture: From Optional to Essential

This study investigates the integration of sustainability into Enterprise Architecture (EA) and its impact on organizational performance. It examines how sustainable EA practices influence efficiency, compliance with environmental regulations, stakeholder engagement, and innovation within organizations. The research employs a structured Likert scale questionnaire targeting professionals in various industries. Findings reveal a positive correlation between sustainable EA practices and improved organizational performance, regulatory compliance, and innovation. However, challenges such as high costs and organizational resistance persist, particularly for Small and Medium-sized Enterprises (SMEs). The study highlights the importance of leadership support and technological readiness in overcoming these barriers. This research contributes to understanding the strategic role of sustainability in EA, offering insights for enhancing organizational resilience and competitiveness.
