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 software requirements definition document should be a functional requirements definition for the software. It should be based on the business functional requirements definition document. The business functional requirements definition document must be formally documented and signed by the business sponsors of the project. The software requirements definition document must be formally documented and signed by project stakeholders.
