What is Product and Product Manager (PM) ?

The product can be anything. PM is not always responsible for the entire product. may be responsible for any part of the product.

Example: There are multiple PMs working on the Facebook newsfeed.

Product Managers are not the managers of anyone, they work for the final success of the product, and they provide communication by receiving feedback from everyone in every field.

PM Types

There are 3 types of PM. The difference is they have different stakeholders. Stakeholders are people who contribute to the product we are developing.

Examples of stakeholder: users, shareholders, lawyers, marketing.
