To build upon the question that they have just asked (see previous question), employers will usually follow up with ..."and how would you attempt to solve the issue?" Identify the components of the issues the organization is facing or may face, and apply your problem-solving skills to address each aspect of the main issue. Being able to formulate a well-thought out reply while showing your thought process step-by-step while being put on the spot will demonstrate a confidence in your abilities to work in that position, and provides insight into your general methodology.
