If you idiot proof something the universe will create a bigger idiot.🙄
I encountered this often while working in IT. For example, 3-1/2 decades ago I created an accounting system on minicomputer systems (Wang and IVPhase), that data entry personnel could enter employee data for hours worked including overtime. Complaints came in to management that salary payouts was incorrect, and blamed my system. I sat down with directors and upper management to watch personnel enter the data.
My system allowed entry of data in different formats, whether it be hours and minutes or fractional hours. Data entry personnel would take timesheets specifying 8.5 hours and enter it as 8 hours 50 minutes, or 2 hours and 30 minutes got entered as 2.3 hours. My system originally allowed a single format, and I accommodated management request to allow multiple entry formats. No matter how much one tried to train the personnel, they still made idiot entries. Solution was to have a supervisor check all entries. Because you can't idiot proof systems.
