A top-down representation of a function or process is known as which of the following?

A top-down representation of a function or process is best described as a Functional Decomposition Diagram. This type of diagram breaks down a complex process into smaller, manageable components, showing how a high-level function can be subdivided into lower-level functions. This approach allows analysts to understand the hierarchy of tasks and visualize the relationships between different functions, making it easier to analyze and design systems.

By using a Functional Decomposition Diagram, system analysts can clearly outline all necessary functional components required to achieve a particular goal, facilitating better planning and communication among stakeholders. Each layer in the diagram represents a more detailed level of the process, helping teams to focus on each individual part without losing sight of the overall objective.
