In this work we have applied the thematic analysis methodology to extract the most relevant conceptions about mathematical modelling practices using the collected opinions from a interdisciplinary team of researchers. The main feature of the team is the use of mathematical modelling in its practice to solve applied problems of the real world. So, five conceptions are obtained, and then all of them were recognized in two of the works published by Poincare's. Consequently, these conceptions represent some key components of the interdisciplinary work supported by mathematical modelling practice.
