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.
Requirements are the users' description of what the finished product, in their eyes, should do. Specification is the technical description of the solution in general, covering the requirements and much more-e.g. cost, technicalities, problems, etc.equirements document what is needed-they shouldn't specify the how, but the what. Specifications document how to achieve the requirements-they should specify the how. In many places these documents are not separate and are used interchangeably.
