There are many ways to answer this question, and if you have a reasonable method of making decisions, it will probably be sufficient. One answer I thought of included not being afraid of askingyour manager. You can follow up by saying even the best needs mentoring, and you always want to improve. So basically, this could work as an answer, but depending on the job, you might have a better shot with an answer like my example.

Short Answers

"I make important decisions by examining all the details and then weighing the pro’s and con’s for each decision."

"I gather all the information I can find and based on the information, I’ll come to the best decision I can. If I know a coworker was in a similar situation, I wouldn’t hesitate to find out the results to make sure my decision is the best one."

"I believe all decisions should be made by having all the information. If you are missing an important detail, it’s easy to make a bad decision. So I make important decisions by having all of the information."

"Important decisions are made by knowledge through information and wisdom through experience. I’ll gather all the information I can find and then apply my experience while analyzing the information.

With this combination, I’m confident I’ll make the correct important decisions."

Long Answer

"I think all decisions are important, and having as much information about the decision is one of the most important aspects. After examining all the facts, I would think about the outcome and consequences of each action and after weighing the pro’s and con’s, I would come to the best decision possible. However, I’m aware that some decisions are not as black and white. In this situation, I would rely on my experience, or even work with my team members to come up with the best decision."

This is a decent answer, but I think you might be able to think of a better one. Feel free to be creative with your answers because those are the answers the interviewer will remember the most.
