When employers interview candidates, they're looking for somebody who can help them make money, save money, or save time. Being able to describe a situation in which you made a recommendation to improve the workflow of the organization will help you stand out amongst the other candidates. This doesn't necessarily have to be a large improvement. It can involve something minor but which helped you or other people do their jobs better. Continuous improvement as a priority with most organizations, and your ability to demonstrate experience in this area will help you during the interview.
