Do Bakeries really have a problem of Product quality inconsistency and, to solve with a recipe standardization tool?

I did a survey recently and one of the Bakery's I surveyed said their customers complain about their food "Not being as good as last time". So, then I asked them about how they would want this problem solved, to which they replied that they wanted a recipe standarization tool. Now I'm confused whether or not they actually need anything like that, because they could just write down their head bakers recipes and hand them out. If my conception of this is wrong, then why? And if so, what features would they need in this recipe standarization tool?
