Reliability engineering
Objectives
The objective of this chapter is to explain how software reliability may
be specified, implemented, and measured. When you have read this
chapter, you will:
■ understand the distinction between software reliability and
software availability;
■ have been introduced to metrics for reliability specification and
how these are used to specify measurable reliability requirements;
■ understand how different architectural styles may be used to
implement reliable, fault-tolerant systems architectures;
■ know about good programming practice for reliable software
engineering;
■ understand how the reliability of a software system may be
measured using statistical testing.
