Question: At my old job, I could sometimes write the documentation before the developers had their meetings. Here, all my guesses are wrong, pretty much all the time. Have I lost my touch?

Answer:
I think the difference is that WAK! is a hardware company that makes manufactured parts rather than a software company that sells an infrastructure or installable application. With software, you get weekly patches over the Internet. Hardware has a certain chaotic yet tangible reality to it, and you can’t dismiss it as easily.

So no, you haven’t lost your touch. Just your self-esteem.
