The maintenance phase of the SDLC cycle involves ongoing support and updates to ensure that the systems function effectively and efficiently. For the Salesforce CRM and ERP systems, maintenance would include having system updates, user support, performance monitoring, and system backups. Regular system updates would require that the systems be updated regularly to ensure they continue to function properly, are protected against security threats, and also reduce bugs that could possibly arise in the system. User support would help users navigate the systems and address any issues or questions that arise. Performance monitoring would allow for the systems to be monitored to make sure they are performing correctly and that any potential issues are identified early before they become major problems. System backups help ensure that data is not lost in the event of a system failure or other events like server crashes or power outages.
