Usually the money saved in description costs is substantially exceeded by the money spend on inspection costs. … There are different types of technical or engineering specifications (specs), and the term is … Various types of designing specifications are the detailed descriptions of the materials, parts, and components to be used in making the product. In a manufacturing firm, when specifications are fixed the final design is also fixed when the final design is fixed; the products competitive stance and its profit potential are also fixed. With the exception of proprietary products, most widely used items are standard in nature; hence, they are highly competitive and readily available at reasonable prices. Within the quality assurance field, there are a variety of different tests. 7 Examples of Quality Specifications. There are three (3) key types of specifications. Purchase descriptions can be classified into two broad categories. Specifications are very important because the cost of materials clearly dictates that their selection is an important consideration during product design. Where quality is based on individual test or preference the bench mark for measurement may be misleading. Copies of standard specifications can be obtained from a number of government, trade association, and testing association sources. Quality standards are defined as documents that provide requirements, specifications, guidelines, or characteristics that can be used consistently to ensure that materials, products, processes, and services are fit for their purpose. ii.
