What kind of chef makes new dishes and makes sure dishes taste the same at different locations?

I once saw an episode of Unwrapped on the Food Network where they interviewed a chef whose job is to make new dishes for restaurants like Chili's and Applebee's. Next he had to recreate the dish with as few new ingredients as possible. Finally he had to find a way to make the dish reproducible so that it always tastes the same regardless of location.
