From the table of contents on Amazon, I saw that in your book you talk about building domain expertise.
Personally I have been in the IT business now for over twenty years and am currently employed as an SCJD/SCEA. Over the years I have found that indeed to make a "good" implementation, even as a developer and certainly as an architect, it sure helps to build up some domain expertise of the project one is working on.
I love the technological part of my job a lot. That is why I find it difficult sometimes to "walk the fine line" between staying a "tech guy" and becoming a "business analyst". I sometimes even feel almost sorry for those "poor guys" who don't get to get their hands dirty anymore on all the exciting stuff that is going on in the Jave EE world.
Did you have that experience also ? What would for you be "the" argument to "switch over to the other side", in either direction, tech or bussiness ?
