These were not being found useful by developing nations of Asia, African and Latin American countries, as these had been developed after taking certain conditions and situations into consideration, which did not prevail in these countries. These models in no way helped in bringing any changes in administrative systems of developing societies which were badly needed by them.
It was in this background that need was felt for developing new concepts and concept of Comparative Public Administration was developed. This concept lays stress on cross-cultural and cross-national administrative studies.
He has developed three broad trends in this regard. He has stressed the need to study administrative system in ecological background so that it was possible to have full understanding of the working of the system. While doing so he has depended on the concepts developed in other subjects Sociology, Physics and Biology, for proposing new theories and models in Public Administration.
