Productmanager (English: Product Manager, abbreviated as PM), also known as product planning, refers to the person who plans and manages a product or a certain type of product in a company, and is mainly responsible for product research and development, manufacturing, marketing and channels. Product manager is a difficult role to define. If it must be defined in one sentence, then the product manager is the person who serves the end user and is responsible for the whole product life cycle.
Product managers need to consider the characteristics of target users, competitive products, whether products conform to the company's business model and many other factors.
Generally speaking, a product manager manages one or more tangible products. However, product managers can also be used to describe people who manage intangible products such as music, information and services. The role of product manager in tangible products industry is similar to that of project director in service industry.
