Chapter Summary

Managers make many different decisions. Every business discipline builds models to help people analyze problems and make decisions. Some models are straightforward; others are complex. Some are described by statements subject to interpretation; others are defined by mathematical formula. Businesses use models to improve their processes, evaluate choices, and forecast the future.

Management information systems can help managers collect data to drive the models. Software tools help managers design and evaluate models. Word processor and graphics software are used to create the final reports. Decision support systems combine elements of these three tools to make it easier for managers to evaluate options, make decisions, and persuade others to accept the decision.
