A solid strategy for answering this question as an IT business analyst would be to discuss your need to continue your education along a certain line of business or technology you would like to learn more about. Of course, be sure to select something that isn't integral to the work you'll be doing if hired for your target role (e.g. don't discuss your lack of Workday expertise if you're interviewing for a role working with HRIS). Alternatively, you can discuss your need to gain more experience in a role you aspire to take on in the future. For example, you may want to expand your knowledge of project management best practices.
