Here is the turn: a pattern is not an explanation. If Monday sales fall while opening times also change, those two facts move together; that does not prove one caused the other. Check the real cause first. Bad numbers produce bad analysis. Then keep your dashboard small: three to five useful indicators, not every number you record. An indicator is a number you watch regularly, and an alert level tells you when it needs attention. Elorm checked her table instead of guessing. Monday sales were down, and the records showed she was opening too late. She changed her opening time. Now the table does more than record Monday. It points to one checked decision. Use trusted numbers to decide what to change.
