Lis further says that as a customer of a UI design firm, you pay for:
- The mesh of knowledge that we have regarding your customer base
- Expertise in knowing how to influence your customers to use your product or service
- Knowledge regarding how to uncover what your users need from you, and how they want to pay for it. To me, this seems like a pretty good deal in the end. Having someone that is a direct input into your making more money.
With a good UI firm, what you are paying for is the ability to not have to worry about an entire aspect of your business.
Lis covers probably three or more distinct but very important topics in a single blog post, which I think deserve separate blog posts. Go read the Lis's post here and come back in a week for part I of the series.
