  A decision is an act or event of decision taking. Decision making always
includes decision taking, the latter not involving significant exchanges with
non-deciding agents. A decision outcome is a piece of storable information
constituting the result of a decision. Decision outcomes are typed, for
instance: plan, command, assertion, or boolean reply to a question. Decision
outcomes are seen by an audience and autonomous actions from the audience is
supposed to realize the putting into effect of a decision outcome, thus leading
to so-called decision effects. Decision outcomes are supposedly expected by the
decider. Using a model or a theory concerning the causal chain leading from a
decision outcome to one or more decision effects may support a decision taker
decision taker in predicting plausible decision effects for candidate decision
outcomes. Decision taking is positioned amidst many related notions including:
decision making, decision process, decision making process, decision process
making, decision engineering, decision progression, and decision progression
production.
