LESSON 1
Question
First define the period, metric, comparison base and management task. Replace “why did things get worse?” with a specific analysis of revenue, traffic and average check.
LESSON 2
Verification
When using an external AI tool, verify its arithmetic and separate facts from hypotheses. Do not share personal or confidential data without appropriate permission.
LESSON 3
Result
State the conclusion with its source, limitation and next step. This lesson teaches an analytical method; it does not imply an AI assistant or document recognition is available in RestaMatrix.
Practical exercise
Average check rose but revenue fell. Which metric is missing?
Check the answer
Check counts for both periods. The reasons for their change need separate investigation.
