Ops professional here. The parent is basically correct, and I'm not sure this is a fair take on what they're saying. To wit, the challenge isn't at the functional level, it's at the integration level. The individual elements are well understood, thoroughly developed and available at scale, but the integration for every factory is, on some level, going to have uniquely differentiated elements. The scoping and management of that is where the challenge tends to sit.
