InfopathIf you work in technology then your probably know that Addison Wesley publishes great books.

InfoPath is a very interesting technology, and one that I think is a little under exposed and documented.

This book is a definitive source for InfoPath power users and developers.

InfoPath is the perfect tool-set for Enterprise developers and power users who need to rapidly develop applications that manipulate their operational data.

This book has great coverage from both perspectives, the power user and the developer.

Make your analysts read the first half and do a user interface prototype (with data constraints and workflow) then you (the developer) can built the final version
