EA to the Power of Three

The EA3 Cube Framework is known as EA3 – “E-A-Three” – which of course is mathematically wrong – we should say “E-A-Cubed”, or EA to the power of three (or to the third power?).

The uniqueness of the EA3 Cube is the singular combination of all its dimensions, functions, levels, components, and other attributes.

  • Levels, sub-architectures, distinct functional areas and their relationships, horisontal and vertical levels
  • Artifacts – the documentation of components at each level of the architecture, including all threads
  • Segments and Lines of Business, the vertical sub-areas of the enterprise with distinct business activities and resources
