For example, is there some process improvement, monitoring tool or logging solution that would reduce firefighting? Something that would immediately help you solve the next issue more easily? Do it while working the issue? Can you rewrite the tickets so they are no longer poorly planned, making them easier and quicker to implement? Do it while working on the issue.
When work is not optimal due to time pressure, there are probably costs related with that. Saving time and resources requires longer-term perspective and making some investment. But often there are things that require only smallish investment, that you can do.
When you save time or resources for your company, re-invest those into some little bit bigger improvements. If you take flexibility and get good results, you will probably be granted more flexibility.
