One characteristic of the Postmodern times (mainly the second half of the 20th century) was "the specialist" and "the specialization". More and more the paradigm of specialization was necessary and sufficient to solve problems and answer questions. The "multi-specialization" was typical of "multidisciplinarity". So, there was a great competition among specialists of the same field, or yet a competition among specialties around of which could be "the best answerer to all questions".
Under the strengh of this paradigm, interdisciplinarity and much more transdisciplinarity seemed to be matter for "poets and philosophers" but not for pragmatists that conducted policy and economy.
But in the 21th century came the depletion of that model and was the end of that kind of efficiency.
So, in the After-Postmodern, specialization and multidisciplinarity are still necessary but they are not sufficient to solve many problems and answer many questions.
In the After-Posmodern, it is necessary a new paradigm to be sufficient to bring solutions to the current crisis.
The interdisciplinarity and the transdisciplinarity can be the tools to achieve a new way to deal with several difficulties.
It means that we still need the specialist, but we now need people that work "transverselly" with the connections between specialties, or within "the net" that goes beyond the limit of the disciplines.
