Assurator provides services for the full lifecycle of a TIA application including application maintenance and support.

Application maintenance is focused on the four primary areas of software application maintenance that are important

for long term stability, sustainability, and maintenance of the TIA application:

Corrective Software Maintenance for fixing issues or defects reported by users  Preventive Software Maintenance for identifying and correcting problems or potential problems before they are noticed by users Perfective Software Maintenance for improving performance and stability of the TIA application Adaptive Software Maintenance for keeping the TIA application usable in a changing environment

Assurator can also extend the application maintenance services by combining them with customer support services and take full responsibility for the support and software maintenance aspects of your TIA application.

The application lifecycle services are orchestrated by an ITIL® based Service desk handling all interaction between the customer and Assurator in a well-defined and structured manner:

• Incident: any occurrence that is perceived by users as a deviation from what they might expect.
• RFS (Request for Service): created when the customer requires a predetermined service.
• RFI (Request for Information): questions that the customer might have.
• RFC (Request for Change) any change to the system configuration or code.
