I’ve published a brief page on orthogonality  here.  I say “brief” because it can take a long, long time to treat that topic right.

See what I did there?

Orthogonality is one of the concepts that allows us to move many aspects of System Engineering from a merely textual exercise to one of math and, therefore, to remove much of the ambiguity that has historically been associated with text-based requirements.  When implemented with reasonable rigor, it enables (therefore) the original notion of “model-based System Engineering”.

In other news…well, there isn’t any other news.  I haven’t touched that workbench in almost two weeks, except to shove it around.  The peanut gallery doesn’t seem to care.

More to come.
