White Paper: One Model

One Model, Many Interests, Many Views

Representing the Journey from Requirements to Behavior Spider Diagram The spider diagramprovides a complete contextual viewof a set of elements and their interrelationships. Unlike a hierarchy diagram, each entity is represented once and only once. In addition, the free-form presentation does not artificially imply a hierarchical relationship that may not exist. The result is an extremely powerful representation – neither traditional nor SysML – for analysis and communication as you continue the engineering journey through systems design.

As with a hierarchy diagram, a spider diagram is based on the combination of a root element and a set of relationships. The element defines the starting point for the diagram. The set of relationships identifies which links to traverse when building the diagram. The relationships (potentially multiple) between the elements are then shown as connecting lines. The lines of convergence and divergence help identify critical aspects in the model.
