The primary purpose of a specification document is to detail the properties of a product or service. This document provides comprehensive information about what is required from a product or service, including specific attributes, performance criteria, and design requirements. It ensures that everyone involved in the development, delivery, or implementation has a clear and shared understanding of what is being built or delivered. This clarity helps reduce misunderstandings and aligns expectations among stakeholders, development teams, and customers.

While other documents might outline business strategy, summarize stakeholder interests, or facilitate communication, the specification document specifically focuses on the technical details and requirements necessary for the product or service. It acts as a guide for developers and serves as a reference point throughout the lifecycle of the project or service delivery. This specificity is crucial for successful implementation, as it ensures that the end product meets the defined needs and expectations.
