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.
