1-11.3 Requirement Specifications

The requirement comprises specifications that are used as its description, including:

• Performance specification (what the product/service is required to do).
• Functional specification (what is to be achieved, rather than how it will be done).
• Brand or trade names.
• Samples.
• Market grades.
• Qualified products.
• Commercial standards.
• Design specifications.
• Engineering drawings.
• Material and method of manufacture.
• Resources.
• Warranty support.

Specifications should be clear and nonrestrictive. Lack of clarity can be misleading and result in poor proposals or a more expensive solution than is necessary. To enhance competition and invite innovation, specifications should be nonrestrictive, mirror what is in the market, and, whenever possible, recommend purchasing commercially.
