Product managers often start with a product requirements document (PRD). A product requirements document defines the product you are about to build: It outlines the product's purpose, its features, functionalities, and behavior. Next, you share the PRD with (and seek input from) stakeholders - business and technical teams who will help build, launch or market your product.
The need for requirements documentation is typically related to the complexity of the product, the impact of the product, and the life expectancy of the software. If the software is very complex or developed by many people (e.g., mobile phone software), requirements can help to better communicate what to achieve.
