I'm curious to know some of the methods that HF or Usability Engineers
document design solutions for products. For instance, I used to work on
the design of printers, and our documentation took the form of written
specifications to describe how the devices worked. If I was working
with something screen-based, visual mock-ups might be my documentation
of choice.

How do you provide your documentation to the developers or mechanical
engineers you work with?
