An information system is a set of interconnected components that collect, process, store, and disseminate information to support decision making and coordination in an organization. Information systems are critical to business operations and success, ensuring improved decision making, operational excellence, competitive advantage, and organizational survival. An information system incorporates three dimensions: organizational, management, and technology. The organizational dimension involves business processes and culture. The management dimension supplies tools and information for managers. The technology dimension consists of hardware, software, storage, and networking that underpin information systems.
