Abstract
While use cases help to visualize functionality, how can you visualize the structure of your learning environment as you develop it? One method to use is the input-process-output (IPO) technique. It is a structured tool with broad applicability throughout the systems development life cycle. This technique uses two different types of charts. The first type is called a Visual Table of Contents (VTOC) diagram and it is used to develop a top-down hierarchical structure through which systems functions and their relationships can be observed, discussed, and better understood. The second type is frequently called an IPO diagram because it describes the input, output, and process components for a given function.
