A manufacturer of computer chips has a computer hardware company as  its largest customer. The computer hardware company requires all of its  chips to meet specifications of 1.2 cm. The vice-president of  manufacturing, concerned about a possible loss of sales, assigns his  production manager the task of ensuring that chips are produced to meet  the specification of 1.2 cm.
