Information systems are a set of interrelated components that collect, manipulate, and disseminate data and information to meet organizational objectives. There are two main types: operations support systems that process transactional data, and management support systems that provide information to support decision making. Key management support systems include enterprise resource planning systems, management information systems, decision support systems, and executive information systems. While information systems provide opportunities to enhance competitiveness, productivity, and quality, they also present challenges around workforce changes, information overload, security issues, and implementation difficulties.
