18.104.22.168.2 - The repository shall have a process for testing and evaluating the effect of changes to the repository's critical processes.
Scholars Portal tests and evaluates changes to its critical processes in isolated development environments to ensure that the repository will continue to fulfill its mandatory responsibilities. Staff evaluate changes for their effect on the integrity of information, the speed and efficiency of the system, and the accessibility and usability of information at dissemination. In addition to automated tests and checks performed by software, Scholars Portal staff manually evaluate changes by examining samples of the relevant content. The repository uses a code versioning system to record changes to software. Moving software from development to production is an automated process. Testing and evaluation continues in the production environment. Solicited and unsolicited feedback from users and OCUL members is another source of information about system behaviour.
Please see the Risk Analysis and Management Strategies document for additional information. The repository has a Backup Plan that describes policies and procedures used by Scholars Portal and the University of Toronto Libraries' Information Technology Services department to provide reliable backup copies of the repository's data, databases, and applications.

There is always a risk of software failure in complex information systems. Scholars Portal uses widely accepted, industry-standard procedures for testing and evaluating software changes, but small errors or conflicts sometimes escape testing. Software failure could force Scholars Portal to suspend certain operations until the affected systems can be thoroughly analyzed, repaired, and tested.
Scholars Portal will monitor changes to critical processes and procedures for compliance with the mandatory responsibilities described in OAIS. In addition, the repository will examine new editions of the OAIS Reference Model for changes to section 3.0.
