Once a while your SAP ERP system may stop working and does not perform well, you can not afford any delay of service or product delivery. To guarantee the system to work continuously you hire a big team of technical supports and they work on sites to safeguard the system. You will pay these specialists a high salary but the system goes wrong only once a while. Therefore it is not cost-effective to keep a team on site. 

DVAS will provide technical support services. This will make the on-site team not necessary. You will also mitigate the burden on managing the team members. This service can be delivered on site or remotely. If the service is delivered remotely, there is no need to provide physical accommodation to the DVAS technical support staff.
