> ...operational achievement, not an engineering one.

How would I distinquish between the two, esp wrt rocketry?

An operational achievement means excellence in building the same vehicle over and over, to the right tolerances, and operating it the same way every time, without fing anything up.

An engineering achievement means excellence in designing a new vehicle, or updating an existing one, or inventing a new procedure, and finding the right tolerances that allow that to be replicated over and over without excess cost.

Aha.

So using some wholly new process, like the continuous innovation involved in casting large parts, how would I separate ops and engr?

Forgive my ignorance. I'm just wondering how Ford's quality circles, or the Toyota Production System would work if ops and engr were treated aa separate silos.

Since we're kibitzing about rockets, I suppose the example above could have been ramping up production of Raptor engines to 1 per day (IIRC), while improving performance and reducing costs. If I wanted to emulate that process, using your methodology, where would I start?
