Rigorous specifications of a good or service are necessary to assure efficient production. Equipment layout and human resources cannot be decided upon until the good or service is defined, designed, and documented. Therefore, every organization needs documents to define its products.

For instance, McDonald's Corporation has 60 specifications for potatoes that are to be made McDonald's French fries.

Basic Principles of Designing Products for Production

Attention to production, CE, and team design are important in obtaining compatibility between the product and the production process. But this is not enough. Those involved in product design need design principles and tools to guide their thinking and to help them evaluate alternative product designs. The overriding principle of product design is "Make it simple!" Simplicity of design and simplicity of the production process can be promoted by using the following principles: -

1. Minimize the number of parts
2. Use common components and processes
3. Use standard components and tools
4. Simplify assembly
5. Use modularity to obtain variety
6. Make product specifications and tolerances reasonable
7. Design products to be robust

In the case of an airplane, as in most manufactured items, a component is typically defined by a drawing, usually referred to as an engineering drawing. An engineering drawing shows the dimensions, tolerances, materials, and finishes of a component. The engineering drawing will be an item on a bill-of-material.
