Product management involves generating, planning, implementing, and controlling a firm's existing and new product efforts to satisfy customer needs while achieving organizational goals. Product managers make decisions about new products to introduce, existing products to modify or discontinue, and branding strategies. These decisions are influenced by factors like customers, competition, the business environment, and a firm's resources. Successful products exhibit quality, competitive pricing, development expertise, and a short development time. Challenges include dynamic markets, time pressures, and investment needs, while barriers are resistance to change, limited resources, reluctance from customers and retailers, and restrictive policies.
