Hotfix
An urgent, targeted correction for a problem in a production system.
What is a hotfix?
A hotfix is a correction initiated at short notice for a time-critical production problem. Its scope should focus on the necessary remedy. Urgency does not remove suitable tests, change review and traceable deployment. Available measures depend on the problem, risk and operating procedure. The term does not guarantee that a change can be made without a restart or interruption.
In a fictional portal, valid reports fail to download after a release. The team narrows down the cause, prepares a targeted correction for the affected version and checks downloading and affected neighbouring workflows. It establishes monitoring and a suitable way back; data changes require their own consideration. The correction must also reach affected versions under further development so that the next release does not reintroduce the same error.
