Thanks for your comment, I really appreciate you taking the time to do so. I like the A Priori concept and agree you need to use what information you have and not be afraid to change your mind if the available information changes.

Decision through indecision eh? It is absolutely true that you can actively decide to do nothing. And this decision can sometimes be the correct course. When you are trying to keep a team motivated and working hard to deliver a project I would venture to say that actively deciding to do nothing is probably not the best way to move things forwards!

Make the decision based on the information available at that point in time.

If furter information becomes available at some
future point in time, modify (or not) your original decision.

Some where in the dim past I remember reading
about decision thru in-decision. In other words
do nothing. This may be somewhat un-systematic,
somewhat like look before you leap vis-a-vis
he who hesitates is lost.
