The development of theories to explain decision-making requires a model that identifies the factors relevant to decision-making. Seven sets of explanatory factors--called the "seven analytical A's"--should be analyzed. They include (1) axiological factors, or those related to values; (2) ten axiomatic factors comprising socioeconomic, territorial, organizational, psychological, and other givens; (3) alternatives, or factors (such as cost, uncertainty, and risk) that influence decisions; (4) "architections," or practical planning factors like titles, persons responsible, specifications, resources, and results; (5) human and material allocation factors; (6) the actions involved in implementing decisions; and (7) the appraisal factors on which evaluations of decisions will be based.
