Ah, that's what the AI ingredient is.

Seems reasonable, the kind of drudge work that gets avoided because nobody wants to do it. Requirements-capture what the existing system does. This often fails in the real world because it's done at some distance: either writing down what they think the system does, or want it to do, or getting political interference to pretend the process is something other than it is, but ignoring the actual working on the ground process.
