This question is asked to determine whether or not you are going to bring something to the team.
In an ideal answer you will confirm that you are creative in your job role, and markedly so compared to some of your colleagues. You should then proceed to give examples which demonstrate this.
This question gives you the opportunity to tell the interviewer about how you developed a Monday-morning prize-giving incentive to get your team fired up for the week. Or how you introduced daily staff meetings to keep your team engaged with the goals of the organisation. Or implemented a buddy-up training programme to help your new recruits settle in faster.
