The CBSP calls these people "Regional Directors". The first time I encountered said person at a small (<50) conference of industry movers and shakers*, he kept using the word "Performant" in relation to whatever-the-hell he was espousing.
Anyway, let's try some etymology:
Perform -> verb. "To do something"
Performance -> noun. "Something done"
Performant -> adj. "Does Something"
Great, the product does something.
Performance -- like quality, temperature, pressure, gravity, and mass -- is a property with no intrinsic position on the good-o-meter.
That's why I can promise that my mission is to:
"Provide Quality and Performant Products".
You have my guarantee!
*I'm not quite a shaker. More of a rattler, really.
