There is a crucial difference between mere financial data and truly useful financial information. Many accounting reports provide too much of the former and not enough of the latter. A theatre management information system should address the questions: “What are the vital measures of our performance concerning ticket sales, production management, development, marketing, and the other factors that determine our financial success?” “How often are those measures updated?” “How current is the information?” “When the ideal information is not available in a timely manner, is there a satisfactory substitute?” This kind of analysis calls for experience with financial information management in complex environments.
