'Guide Decision'

That is the essence of an IT Architect. Your job is to provide a decisionmaker with the best possible option with the least consessions, having assessed the facts, the risks and the demands

Some architects argue that they are merely facilitating the decision making process, but that's selling the profession short. Facilitation stops with a layout of all the given options, including their pros en cons.

But the true passion of an architect lies in conceiving an option that is best for all parties concerned and advocating this option. That's what constitutes the guidance that you are obligated to give, whether it is asked for or not.
