No, product development and product management are two distinct roles that require different skill sets. While both involve the creation, planning and eventual sales of products, the tasks associated with each role vary significantly.
Product development involves the creation of new products. It includes generating ideas, researching and designing prototypes, testing, and presenting the product to potential customers. This role requires technical skills and an understanding of market research, the product's industry and competitors.
Product management is the job of managing the entire product life cycle, which includes brainstorming ideas, setting product launch dates and budgets, marketing, and troubleshooting customer issues. This role requires strong interpersonal and communication skills, problem-solving capabilities, and an understanding of market trends.
In short, product development focuses on the creation of a new product, whereas product management focuses on the management of the entire cycle from beginning to end.
