In a ticketing system, what does the 'ticket summary' field allow?

The 'ticket summary' field in a ticketing system serves as a brief overview of the specific issue or request associated with that ticket. This functionality allows ticket owners to quickly view and comprehend the essential details or status of the ticket without having to delve deeply into the entire ticket's contents. Such a summary is crucial in managing and prioritizing multiple tickets efficiently, enabling quick decision-making and actions regarding ticket resolutions.

The other choices do not accurately define the purpose of the 'ticket summary.' While documenting unresolved issues, assigning additional owners, and calculating resolution time may be related functionalities within a ticketing system, they do not encapsulate the primary role of the ticket summary, which is to facilitate quick comprehension and access to vital information regarding the ticket at a glance.
