What would you do if you are faced with a difficult task that goes beyond your usual responsibilities?

If I face a challenging task that goes beyond my usual responsibilities, I would first try to understand it on my own by studying available documentation and resources. If that is not enough, I would seek help from colleagues or mentors to get advice or recommendations. It is also important to break the task into smaller parts and tackle them systematically. This approach helps to effectively handle new challenges and expand one's skills.
