Specification

A specification is a formal document that defines the requirements, design, behavior, or standards for a system, product, or process, ensuring clarity and consistency in development. It serves as a blueprint for implementation, testing, and maintenance, often used in software engineering, hardware design, and protocol development.

Also known as: Spec, Requirements Document, Design Doc, Standard, Blueprint

Why learn Specification?

Developers should learn and use specifications to ensure interoperability, reduce ambiguity, and facilitate collaboration in projects, particularly when building APIs, libraries, or systems that must adhere to industry standards. For example, following the HTTP specification ensures web applications communicate correctly across different platforms and browsers.
