Boil-the-ocean-ism: All too generic frameworks intended for large-scale program transformation lack local focus and technical guidance.
Architecture astronaut-ism: Abstraction upon abstraction upon abstraction until everything is so conceptual that end-users have dissolved into TOGAF deliverables.
My mantra for solution architecture governance is:
“In IT governance land, it is OK (read: critical!) to be IT- and solution-centric. After all, it is called solution architecture, not conceptual framework theory.”
