ITIL 5 Problem Management: What Changed and How to Run It (2026)

ITIL (Version 5) retains ITIL 4’s definition and three phases of problem management—problem identification, problem control, and error control—but places the practice within product and service management and the Product and Service Lifecycle. It operates alongside incident management in Operate and Support, using incident records, monitoring, observability data, major incidents, and supplier or testing findings to identify actual or potential causes of failures. Teams are encouraged to prioritize problems by business risk, investigate contributing causes, publish tested workarounds as known errors, and route permanent fixes through change enablement, product backlogs, and deployment before closing a problem. The guidance distinguishes reactive work after recurring or major incidents from proactive work based on trends and alerts, and recommends measuring outcomes through repeat incident rates, known-error age, coverage of serious incidents, and fix deployment rates rather than simply counting closed records. AI can assist with correlating incidents, summarizing evidence, and suggesting patterns or possible causes, but human oversight remains necessary for validating causes and approving changes.
