will provide over its useful period of operation. The terminology relates to thetypeof functions that the product is to achieve.Anexample of a functionalspecificationfor a telephone could be: Delivertwo devices that permits voice communication when connected by two copperwires. The device shall permit intelligible information to be transmitted andreceived over a distance of500feet, weigh not more than8ounces, require noexternal power source, and be capable of simultaneous listen andtalkcommu-nication functions.The functional specification provides the seller a wide latitude in acquiring,developing, or building the product. The parametric valuesarenot specifiedand the functions maybedescribedingeneral terms that are subject to interpre-tation by both the buyer and seller. Functional specifications, of course, must beconverted into values that can be used to positively define the requirement ofthe customer.Detailed SpecificationAdetailed specification is one that uses parametric values to describe therequirement. This specification may be developed by the customer or may beone jointly developed by the customer and the seller. This documentisveryprecise in its description of the product.An example of a detailed specification couldbe:Construct one kitchen tableusingallmaple wood and glue that measures40x40inches on the surface andis28inches high. The table shall be one solid piece after integration of the woodsurface and legs. The finish shall be smooth to the touch before applying avarnish coat andthreesubsequent coats.Whencomplete, the table shall becapable of supporting120pounds of weight on the top side when the weight isevenly distributed at not less than four points. The table finish shall be resistantto dents, scarring, or scratching under normal use.The detailed specification becomes involved in the size, functions, andassembly of the product to the level of detail desired by the customer. Materials,integration methods,skill levels of workers, size of product, and durability ofthe product may be precisely stated by the customer.Thisprecision permits theseller to meet the customer's requirements more easily than the functionalspecification because the customer's expectationsareknownindetail.E.SummaryThe ability to meet the customer's requirements depends upon an under-standing of the range of practices for describing a product. Thetypeof customer,the number of customers, and the understanding of the characteristics andattributes of a product are essential to describing products for a mutual under-standing of the requirements. The form of describing the requirements alsomaterially affects the outcome for integrating or building a product. For aproject, the correct combination of the product's attributes and characteristicsto describe the customer's requirements provides the baseline foraqualityproduct.
