Updated by The Dad on January 22, 2015. Recently, in my job as a computer programmer, a customer told me that a system I developed was not working for them. I was shocked because the system was designed to produce exactly what they needed. After some investigation, I discovered the problem. Some users were entering data in the wrong field despite the field label and their training! So, I wrote a little computer code to “idiot-proof” the system and that resolved the issue. I wish I could write some code to “Idiot-proof” the recruiting process!
