It is naive to believe one can, or should, blueprint an enterprise. An enterprise is a complex system that must continually, adapt to survive and thrive.
For any system to sustain, shift, and grow, over time, it requires energies (accelerants), efficiencies, connectors (& disconnectors), and means to remove waste.
Enterprise architecture should focus its attention on fortifying these core functions of the enterprise system, via the infusion of intellectual and digital capability.
Enterprise architecture should capacitate fluidity, not rigidity.
