Good decision making is rarely done by intuition. Consistently good decisions result from diligent accumulation and evaluation of information. Managerial accounting provides the information needed to fuel the decision-making process. Managerial decisions can be categorized according to three interrelated business processes: planning, directing, and controlling. Correct execution of each of these activities culminates in the creation of business value. Conversely, failure to plan, direct, or control is a road map to failure. The central theme is this: (1) business value results from good decisions, (2) decisions must occur across a spectrum of planning, directing, and controlling activities, and (3) quality decision making can only consistently occur by reliance on information.
