A story about spec sheets: part 2

This is an article that continues the story. As we wrote the detailed spec sheet to the engineer, we temporary solved the problem, and he simply follow the check list. However, another trouble came out. He complained that someone changed his file when the deadline approached. That was simply not the truth. No, we didn’t change it, but instead he didn’t even start the project and just want to make another excuse. We finally decided to end the cooperation early because this exotic environment may harm us. Although this was not a happy story, it was a good lesson because we at least learned a lot.
