How can this be better?

Sometimes in an interview we are faced with questions that deal with "....how would you change this?..." At this point we begin contemplating what we've heard and try to make quick decisions about what specific changes we would make if we were in that position.  A goal here is to stay positive and look for ways to improve the situation. Sometimes that could require terminating someone, yet we need to look beyond that obvious answer in light to first make sure they are sitting in the chair that best fits them. If they aren't we may want to see if another slot is a better fit and if not then the obvious is obvious.
When we can keep a positive attitude and give positive input others are quick to see you are thinking on your feet. Of course when you deliver such solutions be sure you speak with confidence, not just reciting answers.
