I saw Todd Warfel speak in August at DELVE UI. I was so inspired by his approach that I changed the way we work. We have now moved away from large decks of wireframes and interaction notes- and embraced the 70% rule. We design 70% then build a prototype. There are a number of examples in my talk Designers vs Developers: Coming together to build the best RIAs. But the point is, if you are designing Rich Internet Applications, RIAs, prototyping is essential.

Check out Todd’s talk on prototyping:

And consider getting his new book, Prototyping: A Practitioner’s Guide to Prototyping, Rosenfeld Media, November 2009. It is full of practical advice and detailed examples, not philosophical musings. If you are like me- a busy consultant who is not a great programmer, but needs to get interactive mock-ups in front of stakeholders as fast as possible- there are a number of great ideas in here.
