I came across the ELMER form design guidelines published by the Norwegian Ministry of Trade and Industry, which gives a pretty comprehensive and reasonably well documented set of guidelines for the design of forms on government websites, which I guess can be generalized to public transaction workflows. However, I don't know if the published date of 2006 means that some of the concepts and ideas are a little bit out of date, especially in reference to mobile device design patterns.
Has anyone else come across similar government standards and what are their thoughts? I suggest that there should be similar standards drafted by organizations like UXPA to set a baseline standard so we don't have to keep debating certain questions here.
