I'm reminded of the work we did for SEPTA (South Eastern Pennsylvania Transit Authority). We did the computer aided dispatch system which had to communicate to the trains via packet radio.
When they showed us the protocol they wanted to use I just about died. No error check, no ACK/NAK. Asked them how we were supposed to test the protocol they said they were going to use a VT100 terminal to type in the messages. I proposed a better protocol and told them we would design an emulator so we could emulate the entire train system.
Then there was one big bugaboo....they had to be able to connect dispatch to all the train's audio systems for emergency announcements and such. I told them they needed a broadcast message and they said "no". I also explained to them that with the ACK/NAK protocol and single train connections it would take up to 30 minutes to get all the trains connected and another 30 minutes to disconnect them (all during which the live dispatch radio system is connected to train speakers). I put this in writing to them. They said "we aren't going to fix it". Around 3 years after we delivered the system they called us and blamed us for the 30 minute delay. I had to haul out the letters between us to show them we warned them.
