The ticket lifecycle

Log & categorise — capture the issue clearly, categorise it (incident vs request), record who and what.
Prioritise — by impact × urgency, against SLAs (Service Level Agreements — the agreed response/resolution times).
Work & update — investigate, keep the user informed, record every action.
Resolve & close — confirm the fix with the user, document the resolution, close cleanly.

Good ticket hygiene (clear notes, correct priority, timely updates) keeps the whole team efficient and feeds ITIL processes and escalation.
