The main use case of ServiceNow in my organization is incident management. Whenever we have any kind of production incident, we manage the lifecycle of that incident through ServiceNow. We create incidents and sometimes create problem records if it is a recurring issue. We handle all follow-ups and updates through this particular incident, so the entire incident lifecycle happens through ServiceNow.
ServiceNow is used for incident management and for creating problem records. It has different integrations with other tools, such as PagerDuty, so we can perform automations easily with ServiceNow.
