8) What is the connection between organizations, information systems, and business processes? Short Answer:
Business processes refer to the manner in which work activities are organized, coordinated, and focused to produce a specific business result. They also represent unique ways in which organizations coordinate work, information, and knowledge and the ways in which management chooses to coordinate work. Managers need to pay attention to business processes because they determine how well the organization can execute, and thus are a potential source for strategic success or failures. Although each of the major business functions has its own set of business processes, many other business processes are cross functional. Information systems can help organizations achieve great efficiencies by automating parts of these processes or by helping organizations rethink and streamline them. Firms can become more flexible and efficient by coordinating and integrating their business processes to improve management of resources and customer service.
