Curative Maintenance

NDS is responsible for maintaining and delivering the PADS4 Software in good working order. Therefore, NDS is obliged to correct any anomaly occurring with the PADS4 Software within the time limits and under the conditions described below.

However, in the event of a critical and major anomaly resulting in a service level below the normal service level, NDS is required to implement a workaround solution within the timeframe set out below. This palliative solution must allow the anomaly to be circumvented and normal service to be returned to a shorter period of time than those provided for the correction of the anomaly.

NDS can only release itself from its obligations under this appendix if it provides proof that the anomalies detected are not due to poor design and/ or construction of the PADS4 Software or that they are due to an act of the Customer.

The intervention may be done on the initiative of NDS or at the request of the Customer by triggering a ticket through the support portal. The Parties agree that the acknowledgment of receipt of the opening of the ticket is proof of receipt by NDS.

The time and date of the request specified on the opening of the ticket constitutes the moment from which NDS is required to meet its Service Level Agreement (SLA) response time commitments.

Anomalies are classified by severity levels:

Critical anomalies: Critical anomalies are anomalies that individually or cumulatively have repercussions on the compliance, quality of service, availability, or performance of the Software leading to rendering all or part of the functionalities of the Software inoperative. Any anomaly affecting the performance of the Software will be considered a critical anomaly.

Major anomalies: Major anomalies are anomalies that individually or cumulatively, although having repercussions on the compliance, quality of service, availability, or performance of the Software, represent a significant hindrance, established on the basis of quantitative data, in the use of all or part of the functionalities of the Software.

Minor anomalies: Minor anomalies are anomalies in the operation of the Software, other than critical or major, with no impact on its use and which may be the subject of requests for improvement of the Software.

Preventive Maintenance

NDS monitors the software and installation and provides proactive support and intervention. In addition, it is required that the intervention does not disrupt the proper functioning, availability and performance of the PADS4 Software in normal service in accordance with its documentation.

All Software Upgrades are maintained for at least twenty-four (24) months from the release date of the next Version Upgrade.

In the event of withdrawal of the Software, NDS will notify Customer at least ninety (90) days prior to the expiration date of the current maintenance period.
