Humans have an innate problem-solving approach: When faced with a problem we don't know how to solve, we try to think of a similar, analogous problem for which there is a known solution. Then, with this known solution in mind, we try to devise an analogous solution to the problem we are trying to solve.

     A real world problem is functionally modeled to define the typical problems. The set of Directions are then applied to selected typical problems to generate a set of abstract solutions. The abstract solutions are evaluated for suitability and combined with resources, to solve the real world problem.
