The power of consumer knowledge
Understanding your customers is a prerequisite to satisfying their wants and needs to increase customer satisfaction in restaurants. Typically we do not know who our customers are; their name, their email, etc. The lack of knowledge keeps us in the dark when constructing menus and promotions, and hinders our ability to measure whether we are satisfying our restaurant customers.
Consumer profiling based on purchase behavior is a technique you can use to see patterns to determine the various types of customers you have, and how you might better service them.
