What are the challenges in defining the boundaries of Enterprise Architecture?

Enterprise Architecture significantly overlaps with several closely related disciplines, including business process management and IT architecture, creating a complex and often intricate landscape that requires careful navigation. In this multifaceted environment, establishing strict, well-defined, and clear boundaries between these fields proves to be quite challenging and often impractical due to their interconnected nature. This considerable overlap underscores the critical importance of fostering close collaboration, maintaining ongoing communication, and ensuring seamless coordination among professionals working within these intertwined areas. Such concerted efforts are essential to develop cohesive, integrated, and highly effective organizational strategies that not only align with overall business goals but also adapt to rapid technological advancements and continuously evolving market demands.
