The state of your marketing and sales
Have you taken a hard look at how sales communicates with marketing and vice versa? Marketing and sales teams don’t need to be competing with each other; they need to be working together. Analyzing how your teams interact and fixing those issues will help out tremendously in the long run and in the short term with your buyer persona development. Your sales team talks with prospects on a daily basis to try and sell them your solution/product. If marketing can understands those pain points, they can create content that speaks to those people. And provide material for the sales team to help make the sale.
