Yritysarkkitehtuuri

Yritysarkkitehtuuri, often translated as Enterprise Architecture (EA), is a conceptual blueprint that defines the structure and operation of an organization. It aims to provide a holistic view of an enterprise's strategy, business, information, and technology. The goal of EA is to align IT strategy with business strategy, ensuring that technology investments support and enable the organization's objectives.

Enterprise Architecture encompasses various domains, including business architecture, information architecture, application architecture, and technology architecture. Business architecture describes the business strategy, governance, organization, and key business processes. Information architecture deals with the structure of an organization's logical and physical data assets and data management resources. Application architecture provides a blueprint for the individual applications, their interactions, and their relationships to the core business processes. Technology architecture outlines the software and hardware necessary to implement business, data, and application services.

By establishing an EA, organizations can gain better visibility into their current state and design a future state that meets evolving business needs. This can lead to improved decision-making, reduced complexity, enhanced agility, and more efficient use of resources. EA frameworks, such as TOGAF (The Open Group Architecture Framework) and Zachman Framework, provide structured approaches for developing and managing enterprise architecture. The practice of EA is dynamic, requiring continuous adaptation to changes in the business environment and technological landscape.
