Broadly, IT service management refers to the way in which IT services are planned and delivered to end users within an organization. This software category covers a wide range of products, with different products focusing on different aspects of ITSM, such as, change management, incident management, knowledge management, and release management. For instance, products focused on incident management help deal with unexpected service interruption issues. There are ITSM software products that help implement ITIL best practices, and the ones that help manage customer support of multiple companies from a single dashboard while also keeping isolation between the different companies. Other notable features include the ability to handle changes in IT infrastructure, the ability to automate ticketing, and the ability to automatically track software availability in an organization.
