11-1 Introduction and Chapter Objectives
In earlier chapters we dealt with quality assurance and control and explored the notion of quality during the manufacture of the product or the rendering of a service. Our discussion focused on a specific instant in time. In this chapter we examine the concept of reliability.
Reliability is a measure of the quality ...
