The primary focus of product management in tech companies is to define and guide the development of products from conception to market launch. Product managers work closely with cross-functional teams, including engineering, design, and marketing, to align product features with customer needs and business goals. They are responsible for prioritizing product features based on market research, user feedback, and strategic objectives. Effective product management ensures that the final product meets user expectations, enhances customer satisfaction, and drives business success by delivering products that resonate with target audiences.
