After marketing a product, they also research c-level contact list whether the consumer has any complaints about the product or whether they expect something more from the product, and whether the product is able to meet the consumer's needs properly. Based on these, they then decide whether any further changes need to be made to the product.

So from this discussion we can say that a product manager is someone who takes all kinds of decisions regarding product management, i.e., a product takes all kinds of decisions related to how it can meet the needs of the consumer in a desired way and become desirable to the consumer, and thus a product manager takes on important tasks. The number of product managers may vary from organization to organization. In large companies, multiple product managers are appointed, while in some organizations, only one position is appointed. So it varies from organization to organization.
