Due to other strategic priorities, the software we had audited had been relatively neglected and the costumer wanted to :

review the "technical debt" existing;
Determine the strategy to implement in order to migrate the software to 4D V15;
Evaluate the investment to set up some features requested by customers.


To achieve this audit we have :

Interviewed the sales team ;
Interviewed the technical team ;
Analyzed the existing code in a contradictory manner with the technical team ;
# Requested an intervention of an additional expert from 4D for the points which had to be validated by the publisher.
