NCV-2 defines capabilities and the composition of capabilities.

Below is an example of a Capability Structure Diagram that describes a capability (Capability-19) that contains two capability compositions (12 and 45) based on other capabilities (respectively 20 and 23).

In the example below, the same capability structure is drawn, however, this time in a tree diagram. By default, composition names are not displayed so that the drawing appears like a tree. It is, however, possible to force the display of composition names, if required (as done for composition-45).
