standard, wide-ranging functionalities that are open and easily adaptable,
widely-extending customizable modules, based exclusively on configurable settings.

This development concept makes DIAPASON particularly well-suited to industries with specific or complex requirements, who wish to base their ERP system on a durable standard, that ensures the sustainability of their investment.
