The FCCAnalyses framework provides a set of tools to study the physics reach of the Future Circular Collider (FCC). It allows users to run through the whole HEP analysis chain from the EDM4hep objects selection to the final plots either on their local machine or on batch. The framework provides a library of common functions written in C++ and a convenient stage based workflow steered with Python.

As more and more people work on the FCC case studies the need for compartmentalization emerges and the framework needs to become more robust. I will discuss the marriage of the C++ analyzer functions with the Python interface in the context of RDataFrame, the various ways of distributing of those functions among the users, efficient work with the Podio and EDM4hep data format, large scale management of the pre-generated input samples, integration of facilities needed to support full simulation studies, and finally other non CLI based modes of interaction with the analysis code.

The talk will be focused on our current analysis setup and how we tackled the various challenges encountered so far.
