What document outlines the requirements for a feature or product?

The correct choice is the document that details the requirements for a feature or product, which is known as Product Specifications. This document serves several key purposes in the product development process.

Firstly, it provides comprehensive information about what the product or feature should accomplish, outlining all functional and non-functional requirements. This ensures that all stakeholders—such as developers, designers, and product managers—are aligned on what needs to be created and how it should function.

Secondly, Product Specifications include technical, usability, and performance expectations, serving as a clear blueprint for the development team. This facilitates better communication and understanding between different departments involved in the product lifecycle, leading to more efficient development processes.

By using clear and formalized Product Specifications, teams can effectively validate a product against its intended purpose, assess feasibility, and prioritize development tasks. This documentation ultimately plays a crucial role in ensuring a successful product launch that meets user and business needs.
