Is the project stuck on convergence?

Just finished Mary Poppendicks book. Good discussion on convergence of the project.

Our project is stuck with a convergence problem. The developers are getting ansi that we won't get the application running and that we may be worrying too much about the last 20% of features.

These are the interesting features for our customers, but also fall out of scope of this first project.

I think we need real data ASAP. That will drive some focus and hopefully early convergence.
