I developed both a website and an intranet solution that approximately 50 civil engineers log into in order to submit files, reports and other internal reports.

One of the engineers called me saying the new solution I had developed was absolutely worthless. He couldn’t even log in. I had sent a very detailed set of instructions in a PDF file, something I thought was absolutely idiot-proof.

After a step-by-step set of instructions over the phone, he resorted to calling one of the secretaries to see if she could log herself in.

As soon as she sat down in front of his computer, I heard her giggling, followed by bursts of laughter by several people surrounding his station. It was minutes before I could get someone to reply on the phone.

Turns out he was trying to log in on the PDF file’s screenshot.
