Responsibility Commensurate with Ability

Designers have the responsibility of being committed to developing experience so that they can function properly. They design products to meet performance and other requirements such as those reviewed in Chapter 4, DESIGNING AND LEGAL MATTER and also RISK. 

Recognize that people have certain capabilities the law says that people have equal rights (so it reads that we were all equal since 1776) but some interpret it to mean equal capabilities. So it has been said via Sun Tzu, The Art of War, about 500 BC Now the method of employing people is to use the avaricious and the stupid, the wise and the brave, and to give responsibilities to each in situations that suit the person. Do not charge people to do what they cannot do. Select them and give them responsibilities commensurate with their abilities.  

The large-production reinforcing fibers used today are glass, cotton, cellulosic fiber, sisal, jute, and nylon. Specialty reinforcing fibers are carbon, graphite, boron, aramid, whiskers, and steel. They all offer wide variations in properties, weight, and cost. 

Fibers in RPs are primarily used to reinforce a resin by transferring the stress under an applied load from the weaker resin matrix to the much stronger fiber. Plastics provide valuable and versatile materials for use as matrices, but other materials, such as metals, ceramics, and cements, are

Biorecognition is the ability of a biologically derived entity (molecule or pathway) to repro-ducibly identify an analyte target and to generate a predictable response commensurate with that recognition reaction.
