HERE IS THE ANSWER TO THE BUSINESS CARD PUZZLE:

William of Occam (ca 1285 - 1349) was an English monk and philosopher who made use of a principle that now bears his name.

"Pluralitas non est ponenda sine neccesitate"

In English this is often rendered as:

"Entities should not be multiplied unnecessarily"

Basically this means that a theory should not carry any provisions that are not strictly necessary.  Any superfluous elaborations should be 'shaved' away.

Now William was using this principle in theological debate and had no notion of its being used in management practice.  Nevertheless, the principle has been adopted by many causes and is often deployed in scientific endeavours.

Einstein had something similar in mind when he said; "Things should be as simple as possible; but no simpler!"

A more modern take on the principle is KISS (Keep It Simple, Stupid!)

This principle underpins the TDS approach; we aim for effective solutions that are as simple as possible: 'Aligning Engineering Practice with Business Endeavour'.
