When you start a new position, it is essential to be clear on how you will make a positive impact after being hired. This question is a delicate one, and you need to show respect for the onboarding process, then give a moderately ambitious project that you could execute. This concept is often called your 'value proposition' in marketing. 'Hire me because I'll do X.'
Remember, this is your campaign promise. If hired, it will likely be your first target to hit, and depending on the environment; it could make or break you. The best approach is to give a functional analysis of the employers' needs and your skills.
Tell the interviewer what your impact goal is, should you be the successful candidate. Be sure to refer to the immediate needs of the company, such as increasing budgets, or improving patient care, for instance.
