Business Processes
Business processes are the collection of activities required to produce a product or service. These activities are flows of material, information, and knowledge among the participants in business processes. Business processes also refer to unique ways in which organizations coordinate work, information, and knowledge, and the ways in which management chooses t coordinate work. To a large extent, the performance of a business firm depends on how well its business processes are designed and coordinated.
How Information Technology Improves Business Processes
Today, information technology can do much more. New technology can actually change the flow of information, making it possible for many more people to access and share information, replacing sequential steps with tasks that can be performed simultaneously, and eliminating delays in decision making. New information technology frequently changes the way in business works and supports entirely new business models.
