Each flow zone is linked to a specific component of your project. 

The project is composed of two main blocks:
- [Flow zones / rfm](article:24): These flow zones are mainly dedicated to learning the RFM scoring method on a reference period. 
- [Flow zones / rfm propagation](article:25): These flow zones are mainly dedicated to applying the RFM scoring method over a larger period: this is what we call in this project the "RFM propagation".
