Document Summary

Reasons for growth of decision-making information systems: people need to analyze large amounts of information. Improvements in technology itself, innovations in communication, and globalization have resulted in a dramatic increase in the alternatives and dimensions people need to consider when making a decision or appraising an opportunity: people must make decisions quickly. Time is of the essence and people simply do not have time to sift through all the information manually: people must apply sophisticated analysis techniques, such as modeling and forecasting, to make good decisions. Information systems substantially reduce the time required to perform these sophisticated analysis techniques. Strategic - granularity refers to the extent of detail in the information (means fine and detailed or coarse and abstract information) Occurs in situations in which no procedures or rules exist to guide decision makers toward the correct choice. Employees evaluate company operations to identify, adapt to, and leverage change.
