In this research I tested for differences in data and information needs at two different organizational levels. I used the makeup of data and information to measure these differences. I first defined data, information, and the makeup of data and information, since the literature doesn't consistently define them. I selected endeavors as a surrogate for organizational levels, since endeavors relate to what managers do, not where managers are in the organization. I related data and information needs to different endeavors, and developed testable hypotheses to measure and test differences in data and information makeup for two different specific endeavors. I designed an experiment in which subjects ranked tasks (a strategic endeavor) and then used the same tasks to develop a weekly schedule for an employee (an operational endeavor). Subjects were selected from managers at Management Systems Laboratories, a research organization at Virginia Tech. As subjects performed the experiment, they were asked to verbalize what data and information they used off the test documents and how they used it to perform each endeavor. Using my definitions of the makeup of data and information, I found that subjects ranking tasks used 1) more information as a percentage of all data and information used; 2) more references to evaluate each indicator; and 3) more references external to the task scope, expressed as a percent of an references used, than subjects developing a weekly schedule. I was not able to show that managers ranking tasks use more data and information than managers developing a weekly schedule. / Master of Science
