Assume you are an art director at an advertising agency, where your responsibilities are working with various copywriting partners to brainstorm the concepts for new ads and then working on your own to design the visual elements of the ads. The ads you work on tend to get rave reviews from clients and have been a key factor in landing two new clients that brought the agency a lot of additional revenue. In light of your successes, you believe you deserve a raise. Describe the steps you would take to prepare for a negotiation on this matter with your boss.
