Clients are from Venus, developers are from Mars

Things to keep in mind:

Through my life as a software developer, usually my clients did not possess the same technical skills that I did.

They did not take “Systems Analysis and Design” course in collage, and they could make very little sense out of UML diagrams.

Blueprints and such are waaaaay to abstract for them.

And guess what? I also lack their knowledge. At best I had a vague idea about their field, and about the domain of their problem which the project I was working on should have addressed.

we speak different languages.

You too, dear reader. Yup.

See the “How many points” problem to understand the possible mismatches you can have when interpreting abstract models.

So if a developer (or a software company, whatever) provide a client with a thick “project analysis” paper, loaded with, ehm, blueprints, UML diagrams and such, then after wasting a lot of time on arguments, the client will sign on a spec he did not comprehend fully, and does not correlate with his needs and whishes.

At the end of the development phase you’ll get a product that do not incorporate the domain knowledge, and give a partial solution to the client’s pain. The client’s satisfaction will be “arrr, that’s O.K.” at best. Even it will have super-duper-shiny-ajax-powered-SOA-2.0-3D-effects-with-silverlight/wpf/air/flash-thingy

After the ‘cool’ effect is over, the client just have to learn to live with the not-perfect solution

The only a possible recipe for dealing with that:
