This document discusses key concepts related to new product development and product management. It defines a product as anything that can satisfy a want or need in the marketplace. New products are described as new to the world, new product lines, additions to existing lines, or improvements/revisions to existing products. Reasons for developing new products include growth, competition, excess capacity, and profitability. However, reasons for new product failure include being a "me too" product, lacking superiority, price resistance, poor market research, and rushing to market with defects. Product management involves product planning, development, branding, and the product lifecycle. The goal is to identify opportunities and create, deliver, and retain value for customers.
