Should everyone know how to code?

Software development teams typically include highly technical individuals and non-technical users. This presents a fundamental communications problem. We probably all know someone in each camp....a programmer who, while brilliant with code, is not a good "people person" and someone who is a subject matter expert on a business process but not very savvy when it comes to technology. Both are essential to the success of the project. We need to bridge this gap. Some might suggest that everyone should learn how to code, almost from birth! That seems a little unfair as if we are expecting the business side to learn how we do things on the technical side. But, then again it might just work over time. In the meantime this is still a challenge. Do you believe that the Unified Process based on Object-oriented development provides us with the best way to help all project team members speak a "common language"? Why or why not? Do you have any other suggestions for improving understanding among team members?
