Perhaps you can reassure them without numbers by demonstrating some of the problems first hand. I'm sure you remember the [apocryphal story about the] video of two guys who can't figure out how a copier works, and then it turns out that they're both Nobel Laureates, so if they can't use it, who can? I believe this is less of a "I need numbers" problem and more of a rhetorical one. When you've identified key shortcomings and pain points in the existing solution, use them as a starting point for your argumentation, which builds towards a specific and well-considered investment in design.
There are many different rhetorical models that you can use to convey your insights and convince your audience. Pick the one that works best for you and create a line of argumentation that makes honest, accurate and effective use of your findings and justifiable beliefs. Data can support an argument, but it cannot replace it. ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)!
