As far as construction, in the most basic sense of that term, it seems like a good resource.

However, the tricky part isn't constructing forms, it's asking the right questions in the right way. Surveys are perhaps the easiest way to go wrong there is.

"Self-reported data is extremely weak and three levels removed from the truth". Why is this? People lie on surveys and focus groups, often unwittingly.

A little story. A handbag designer produced a focus group and survey for deciding which bags they should offer for the upcoming season. They had the participants go through the process. As a casual aside, they allowed each participant to take one handbag as they left -- as an expression of the company's appreciation.

They then threw out the survey and counted which bags had been taken.

The web is great for automating with great efficiency the stuff you should not have been doing at all.
