Which of the following is NOT an activity of an Information System?

An Information System encompasses a series of activities that help in managing and processing data to facilitate decision-making and improve efficiency. Each of the activities listed plays a crucial role in the functioning of an Information System.

Input refers to the gathering and capturing of data that is necessary for processing within the system. Output involves delivering processed information to users, providing them with the insights needed to make decisions. Feedback is an essential process that helps to assess the effectiveness of the information provided and leads to necessary adjustments in the system or operations.

Analysis typically refers to the examination and interpretation of data but is not categorized as a core activity of an Information System in the same fundamental manner as input, output, and feedback. The core activities are focused on the flow and management of data rather than the scrutiny of data itself, which is more a process conducted after the primary activities of the Information System have taken place. Thus, while important, analysis is generally seen as a result of processing rather than a foundational activity of an Information System.
