During which technical process are N2 diagrams commonly utilized?

N2 diagrams, or N-squared diagrams, are primarily utilized during the architectural definition phase of system development. This technical process involves defining the system architecture, establishing the relationships and interfaces between different system components, and ensuring that all parts of the system work together effectively.

The use of N2 diagrams is particularly valuable in architectural definition because they provide a visual representation of how components interact with one another. Each axis of the diagram typically represents a system component, and the intersections demonstrate the interactions or data flows between these components. This clear visual layout helps engineers identify and analyze component dependencies and communication pathways, which is essential for creating a coherent and functional architecture.

In contrast, during feasibility analysis, the focus is on assessing whether a proposed project is viable and worth pursuing, rather than detailing the architecture of the system. Component testing deals with evaluating individual components after they have been developed, ensuring they meet their specifications, rather than their interactions within the complete system. Finally, system verification entails ensuring that the entire system meets the required specifications and fulfills its intended purpose, which occurs later in the development cycle after the architecture has already been defined.
