This is a general question. It doesn't ask if you are the one with the conflict, if it is a conflict with another person, if it is a conflict of schedule, or if it is a conflict with changes at work. If you want, you can ask a question to clarify. But if you want to answer in a general way, try to think of an answer that will work for all types of conflict.
This is an answer that could be applied to all types of conflicts. It doesn't state the exact situations of each conflict, but it does state why following a process is good. The interviewer will not think this is an original idea. However, the answer provides reasons why it helps. These reasons are the key to the answer and it shows that you are organized and in control. This answer, without the last sentence is just mediocre. But the last sentence makes is very strong.
