This document discusses the importance of developing a marketing plan that identifies target, secondary, and tertiary customer markets based on demographics like age, gender, income, and consumer behaviors like online shopping. It emphasizes identifying what problem the product solves for customers rather than just the product itself. A successful plan will ensure the product meets the needs and budget of the target market and uses various promotional strategies across social media, print, and traditional outlets. Developing an initial prototype is also an important step before launching.
