“The problem solver needs to stand back and examine problem contexts in the light of different “Ws” (weltanschauungen). Perhaps he can then decide which “W” seems to capture the essence of the particular problem context he is faced with. This whole process needs formalizing if it is to be carried out successfully. The problem solver needs to be aware of different paradigms in the social sciences, and he must be prepared to view the problem context through each of these paradigms.”
