The fact that we’re in a people-heavy and asset-light industry means that these synergies are often people-related doesn’t make the use of the term improper or a euphemism any more than any other industry common term.
I guess technically if you combine two companies and accomplish the same thing but more cheaply due to overlap the company is therefore "greater" but you see where the meaning is already watered down from its original intent. This is elimination of redundancy, not synergy.
"This merger will result in a big ROI due to redundancy that can be eliminated" is the proper way to say it. Not "This merger will realize a number of synergies". Hence the euphemism comment.
I would characterize that as removing redundancy. Synergy has a different definition altogether.
> the interaction of elements that when combined produce a total effect that is greater than the sum of the individual elements, contributions, etc.
When an intended effect of a for-profit company is profit and a combination of two companies becomes more profitable (has a greater total intended effect) as a result of the combination, how is that altogether different?
Synergy's eventual heat death was, I'd hypothesize, greatly accelerated due to its preponderance in merger announcements and consulting decks in the 80s, 90s, and 2000s.
Would be nice to use it again without caveats. Maybe one day.
