[Editor's note: This help articles previously linked to from this post have since been replaced. For more information about ticket fields, including Tasks, please view this article].
Task is a ticket type alongside Incident, Problem and Question, intended for work orders, change tasks or projects. Tasks can carry due dates, available for all workflow and business rules in Zendesk. All help desks now have two (inactive) views that display current and overdue tasks. The due date-field can also be utilized for setting up alerts and notifications (via automations) to end-users or agents, when tasks are imminent, or for when tasks are overdue. Agents can now jot down notes on customers and customer-organizations from the context of a ticket.
