Requirement

Specification

specific record of a set of requirements 

specific record of a design

a requirements specification is the artifact that contains the specified requirements as a set, for the item which is the subject of the requirements specification.

Specification is subset of requirement

In new product design, a requirements specification for the product would normally drive that design. Once design of the product is implemented, verification of the product will be carried out against the requirements specified in the requirements specification.

The activity of design creates requirements on elements of the solution, e.g. on a subsystem. The requirements on a subsystem will normally be extracted from the design and specified as a set for the purpose of communicating the requirements on the subsystem to the designer or supplier of the subsystem
