Problem's problem

The Learning Primacy Principle illustrates the severity of the Problem's problem. The Problem's problem is that the Buyer does not yet know the best way to solve their problem; therefore the Buyer cannot move ahead with solving the problem.
Where does the Buyer look first? What information should they consider? Can the problem be solved internally, with existing resources? If so how? If not, what else is needed? And once the project of Curating Expertise is begun will it yield results? Will the best solution be found, or will it have been a lost effort?
