LESSON 1
Goal
Decide whether you need convenient menu browsing, ordering, payment or review collection. These actions require an appropriate service; use RestaMatrix for analytical context.
LESSON 2
Measurement
Compare completed orders, average check and errors before and after implementation. Separate interface changes from simultaneous price increases.
LESSON 3
Feedback
Group reviews by topic: speed, food, payment and service. Check the number of responses: a few ratings do not represent all guests.
Practical exercise
80 out of 100 started orders were completed. What is the completion rate?
Check the answer
80%. Compare periods with the same definition of start and completion.
