Why Omega Alpha?

In contrast to Alpha Omega, what does the reverse usage imply for Systems Engineering?

Systems Engineering (SE) may be defined and described as:

A technologically based interdisciplinary process for bringing systems, products, structures, and services (human-made entities) into being. While the focus is nominally on the entities themselves, systems engineering employs an expanded strategy. Systems engineering inherently considers the end before the beginning and concentrates on what the entities are intended to do before determining what the entities are, with form following function.

“Think about the end before beginning” from the philosophy of Leonardo da Vinci
