  Knowledge is only good if it is sound, consistent and complete. The same
holds true for conceptual knowledge, which holds knowledge about concepts and
its association. Conceptual knowledge no matter what format they are
represented in, must be consistent, sound and complete in order to realise its
practical use. This paper discusses consistency, soundness and completeness in
the ambit of conceptual knowledge and the need to consider these factors as
fundamental to the development of conceptual knowledge.
