A specification is a detailed description or set of requirements that outlines the characteristics, features, and criteria for a product, service, or project. It provides clear instructions and guidelines to ensure that the desired outcome is achieved. Specifications typically include technical details, measurements, quality standards, performance expectations, materials, and any other relevant information necessary for the successful completion of the task or deliverable. Specifications serve as a reference for stakeholders, suppliers, and project teams, enabling effective communication, clarity, and consistency in understanding and meeting the desired objectives and standards.
