Agile is from 2001. What you seem to be thinking of is the Toyota Production System. It is quite possible that TPS inspired Agile, but to claim that it is Agile is like saying that GPT is from the 1960s (because it shares some resemblance to Eliza).

Yeah, the Toyota JiT stuff, but the company I worked for is a 100+-year-old engineering corporation, and didn't do stuff in no new-fangled, 1950s-kid-playground way.

But the term "Agile," is a lot more recent (and US-based). I rapidly learned never to use that word within earshot of my managers. Sort of like saying "California Roll" in a traditional Tokyo sushi joint.
