Enterprise architecture (EA) is a strategic discipline that defines the structure and operation of an organization. It provides a comprehensive framework to align business processes, information systems, technology infrastructure, and governance with the organization's vision and objectives.
Key Characteristics of Enterprise Architecture:
Holistic View: EA looks at the entire organization as an interconnected system, considering all aspects—business, data, applications, and technology, or in short, BDAT.
Alignment: It ensures that IT investments and operations are aligned with business goals and deliver value.
Framework-Driven: EA often employs frameworks like TOGAF, Zachman, or FEAF to guide its structure and methodologies.
Transformation Focus: EA supports change management by providing a clear roadmap for achieving future states while minimizing risks.
Purpose of Enterprise Architecture:
Strategic Decision-Making: Supports leaders in making informed decisions about IT investments and organizational changes.
Operational efficiency: streamlines processes, reduces redundancies, and enhances interoperability.
Adaptability: Enables organizations to respond to changing business environments and technological advancements.
Risk Management: Identifies and mitigates risks associated with IT and organizational changes.
