An issue tracking system (also called trouble ticket system or incident ticket system) is a computer software package that manages and maintains lists of issues, as needed by an organization. Issue tracking systems are commonly used in an organization’s customer support call center to create, update, and resolve reported customer issues, or even issues reported by that organization’s other employees. An issue tracking system often also contains a knowledge base containing information on each customer, resolutions to common problems, and other such data. An issue tracking system is similar to a “bugtracker”, and often, a software company will sell both, and some bugtrackers are capable of being used as an issue tracking system, and vice versa.
