A ticketing system in IT support is a software tool used to manage and resolve technical issues reported by users. It allows users to submit requests, commonly known as "tickets," for support or service, which are then tracked throughout the resolution process. The system prioritizes and assigns tickets to technical staff or support teams, facilitates communication, and allows for efficient tracking of issue status. This organized approach helps improve response times and ensures that no requests are overlooked, ultimately enhancing user satisfaction and operational efficiency.
