Assuming you are following a design methodology such as the IxD iterative approach which covers requirements gathering, prototyping, evaluation etc.
This creates a lot of information (data) usability and user experience goals etc, functional and non-functional requirements begin to appear. How do you collate / record all this information to produce the final design specification? Is there an industry standard pro forma?
I could create my own, however if we all did that I expect developers would get hacked off with reading specs in many different formats.
