Business Architecture

The Business Layer defines the strategic and operational foundations of an enterprise. It describes what the organization aims to achieve, how it organizes its operations, and which actors or roles carry out those operations. This layer is independent of technology and focuses on goals, responsibilities, processes, and capabilities.

It serves as the foundation for aligning information systems and technology with the organization’s mission and value delivery.

Purpose

The Business Layer answers the questions:

  • Why does the organization exist?
  • What does it want to achieve?
  • How does it operate to achieve that?
  • Who is involved in those operations?

These concerns are captured through key architectural concepts.
