There is still much discussion in the Cross-Platform Development literature about benefits and applications of tools and approaches.

The purpose of this study is to describe and analyze the practices and relationships of professionals responsible for selecting these tools for the development of their projects.This research is conducted by Felipe Munhoz Afonso and Daniel Lucrédio ( http://www2.dc.ufscar.br/~daniel/ ) at the Federal University of São Carlos (UFSCar) - Brazil and was approved by UFSCar internal Ethics Comittee.
