The final step in incident handling, closing the incident, is often rushed. Making sure to write a detailed solution in your tracking system in a way to make it usable for yourself and your colleagues in the future will end up making your life much easier. Making a habit of updating the incident and adding missing comments before closing it will pay off in the long term. If your tracking system supports it, you should also make the incident available in the knowledge base if you were not yet able to find related incidents during your research.

One thing should never be forgotten; you should always summarize the solution for the user and provide them with information how to refer to this issue and how they may solve it themselves if it happens again. Make sure to provide them with information about things you were unable to determine as for the cause of the issue so that if it happens again they know what to look for as it is happening.
