What is the purpose of an N-Squared Diagram?

The purpose of an N-Squared Diagram is to facilitate the visualization and analysis of relationships between different elements in a system, particularly actions and their corresponding inputs and outputs. It captures how various components or entities interact with each other, making it easier to understand complex interdependencies and communication patterns within a system. By organizing this information in a matrix format, practitioners can quickly identify where interactions occur, which is crucial for systems engineering, especially during the early stages of system design and integration. This diagram supports the identification of both functional requirements and the interfaces required for system components to work together effectively.
