Processing customer orders
Michael believes that his data analysis is accurate but it took a lot of
effort:
The servers wrote customer orders on multipart paper checks
One copy went to kitchen for meal preparation
The server tabulated totals on the original copy and gave it to
the customer when the meal was complete
The customer paid the cashier directly with cash or a credit
card. The hard copy of the check is saved
Several times a week, Michael used the paper checks to enter the
sales and table information in an Excel spreadsheet for analysis
Michael is busy with operational work, the Excel data entry and
analysis if often delayed
