The business strategy is most important to the architecture’s long and
short term goals. The ideas expressed in the architecture must hold for a
period of time that is at least as long as, and preferably longer, than the
usual planning horizons.1 That’s why as a minimum we must explore that
part of the planning period that is more or less clear, and the business
strategy contains that. Therefore architecture scope and objectives and
thus the whole architecture engagement should be aligned with the business
strategy.
