PURCHASE DESCRIPTIONS

Purchase descriptions serve two purposes. They allow the buyer to determine what to buy and where, as well as allow the vendor to quote properly and deliver the correct item. Adequate item descriptions ensure you get what you need at the best value possible. Item descriptions, specifications, and technical requirements should always be clear and concise. Describe your requirement in sufficient detail to leave no room for doubt. Ambiguous descriptions delay contracting action and can lead to the purchase of the wrong product or service. Correcting discrepancies is time consuming and expensive, it wastes your valuable time and the Contracting Officer’s.

Item descriptions set forth the essential physical and functional characteristics of the supplies or services required. The minimum requirements of the government should be expressed in the description. However, do not confuse minimum requirements with minimum descriptive data. Include as much information as possible to describe exactly what you need. The principal features of a purchase description may be determined by answering such questions as:

· What is it?

· What is it made of (paper, wood, plastic, etc.)?

· What are its principal descriptive characteristics (size, color, shape, etc.)?

· What does it do?

Preparing a Purchase Description A generic purchase description is written in simple language, such as you would use in your own private purchases. Brand names are prohibited without separate written justification. A generic description is the most desired, in that it clearly identifies what is required, yet provides for the maximum competition among available sources. The purchase description should clearly describe the essential physical and functional characteristics of the item required. It should include as many of the following characteristics as necessary to express the minimum requirements of the government:

· Kind of material

· Electrical data, if any

· Dimensions

· Restrictive or significant environmental conditions

· If part of an assembly, the location within the assembly

· Essential operating conditions

· Special features, if any

· Operation to be performed

· Equipment with which the item is to be used

· Should there be a warranty?

· Does it need to be setup and/or installed?

Brand Name or Equal If, however, you cannot write an adequate purchase description, a less desirable alternative exists by identifying a specific product followed by the words "brand name or equal."

Brand name or equal purchase descriptions must include, in addition to the brand name, a general description of those salient physical, functional, or performance characteristics of the brand name item that an “equal” item must meet to be acceptable for award. Use brand name or equal descriptions when the salient characteristics are firm requirements.
