These steps are not necessarily taken in precisely this order, nor are all of
them necessarily significant in every problem. However, an effort to define the
ptoblem is usually the tight starting place, and telling the story is almost inevitably
the ending point. Constructing alternatives and selecting criteria for evaluating
them must surely come toward the beginning of the process. Assembling some
evidence is actually a step that recurs throughout the entire process, and it applies
particularly to efforts to define the problem and to project the outcomes of the
alternatives being considered.
