This presentation discusses formal and informal information systems. Formal systems have clear workflows, communication flows downward, and authority levels. Information flows from bottom to top management. There are three categories of formal information: strategic, managerial, and operational. Informal systems are employee-based and designed to meet personal needs and solve work problems. They funnel information upward through indirect channels like conversations, rumors on social media, and lunch discussions. The main differences are that formal systems are organizationally represented with documented procedures, while informal systems are employee-based and revealed through observation.
