I wish....
For me, a new item is AT LEAST a 10+ page document with every raw ingredient, every prep item, every recipe, every detail, every comp/promo, pictures of the plates, where the buttons go, what the buttons say, what the server should say about it, what pairs with it, go-live dates, test dates...
Unfortunately, it's all necessary for Marketing, Accounting, Operations, Training, IT, Purchasing, etc...
It wouldn't make any sense for me to share it, for MANY reasons. For example, we have more than one POS system. (And also, it's ridiculous.)
I think these are going to be too specific to your needs. But I feel your pain, let me assure you of that!
