Enterprise architecture serves as the guiding framework for both business processes and IT infrastructure, embodying the integration and standardization needs of a company's operating model. It offers a holistic, future-oriented perspective on a company's processes, systems, and technologies, enabling individual projects to enhance capabilities beyond immediate requirements. The evolution of companies in adopting an enterprise architecture approach unfolds across four stages: Business Silos, Standardized Technology, Optimized Core, and Business Modularity. Progressing through these stages elevates the strategic significance of a company's execution foundation.
