A specification is a document that outlines the requirements, standards, and details of a product or service. The term 'specification' can be broken down into three parts: STANDARD (8 letters), DESCRIPTION (11 letters), and DETAIL (6 letters). A STANDARD is a set of criteria that must be met in order for a product or service to be considered acceptable. A DESCRIPTION is an explanation of the features and characteristics of a product or service. Finally, DETAIL is a more precise explanation of the features and characteristics of a product or service. Together, these three components form the basis of a specification document.
