I understand that chefs can gauge the quality of a dish by monitoring its popularity. However, suppose a chef wants to improve an existing recipe, how might he/she do that?
Will the chef rely on customer feedback? Suppose a customer says he likes the steak but thinks the sauce can be improved. How can a chef use that information?
Clarification - I want to understand if and how chefs might use customer feedback to improve dishes.
Suppose a chef surveys 100 customers. 60 of them say that the steak sauce need some improvement. Will the chef investigate further to improve his recipe? If so, how would he do it?
Also, suppose that the same 60 customers say that they prefer the steak sauce in another restaurant, will the chef go to the another restaurant to investigate?
I'm not senior enough to leave comment, so thanks to everyone that tries to help!
