  2. Recognize the Problem
    The starting point in rational decision making is recognizing that a problem exists.
    Some years ago, for example, it was discovered that several species of ocean fish
    contained substantial concentrations of mercury. The decision-making process began with
    this recognition of a problem, and the rush was on to determine what should be done.
    Research revealed that fish taken from the ocean decades before and preserved in laboratories
    also contained similar concentrations of mercury. Thus, the problem had existed for a long
    time but had not been recognized.
    In typical situations, recognition is obvious and immediate. An auto accident, an over-
    drawn check, a burned-out motor, an exhausted supply of parts all produce the recognition
    of a problem. Once we are aware of the problem, we can solve it as best we can. Many firms
    establish programs for total quality management (TQM) or continuous improvement (CI)
    that are designed to identify problems, so that they can be solved.

  3. Define the Goal or Objective
    The goal or objective can be a grand, overall goal of a person or a firm. For example, a
    personal goal could be to lead a pleasant and meaningful life, and a firm's goal is usually
    to operate profitably. The presence of multiple, conflicting goals is often the foundation of
    complex problems.
    But an objective need not be a grand, overall goal of a business or an individual. It
    may be quite narrow and specific: "I want to payoff the loan on my car by May," or "The
