In French: rétrospection informatique.
This IT management policy provides a study of the IT costs due to each department, to the managers and executives of the organisation. This analysis makes it possible to manage the IT costs with the managers without actually re-invoicing each department.
This method, which appeared around 2010, consists of tracing data to fill the limits of chargeback, and reduce the pressure on departments to reduce their consumption.
This practice has positive effects in restoring transparency and trust between operational and management teams.
