Do interactive systems need specifications?

The obvious advantages of prototyping and incremental development for interactive systems lead some people to believe that specifications of such systems are unnecessary or even harmful. I question whether there really is a conflict between specifications and prototypes. In fact the two schools have more in common than is usually supposed. Both specifications and prototypes can be understood as theories about the system to be developed. Both have important and complementary roles in development.
