• There are relationships between the various cells. The primary relationship between cells on the same row is one of "consistency". In other words, artifacts for the same "topic" must be consistent with each other across the row. This applies primarily from the Analysis level, through the Logical and Implementation levels.

• Relationships between cells in the same column is one of "traceability". Artifacts from the Analysis row must be traceable to equivalent reference artifacts, Logical artifacts must be traceable to their associated Analysis artifacts and Implementable designs must be traceable to their logical equivalents.
