The fundamental aspects of the decision making process. First, the problem is defined, relevant objects are observed and classified, measurements of their activities are taken, and the data is collected into a database or file so that the decision maker can understand the problem. From this data, functional relationships are developed from various models and predictions, or inferences are made. Criteria are selected for decision making and for appealing to various alternatives. Based on these criteria, a decision model is used to select the best or most satisfactory alternatives or courses of action. Management measures are then taken. Finally, an accounting system is used to measure the outcome of the action and to feed the results back into the decision process so that management makes the next decision. In some cases, many of these processing steps are automated. In other cases, they are carried out by the decision maker based on information provided by the accounting information system and computer software used to assist management in the decision-making process. Throughout the decision-making process, there are communication channels through which information flows, and there are numerous feedback loops for more information about the results of actions and their influence on future decisions.
