Reliability Evaluation of Web Based Software

The IEEE defines reliability as "The ability of a system or component to perform its required function under stated conditions for a specified process time". To most project & software development managers, reliability is equated to correctness, that is, they look to testing and the number of bugs found & fixed. Web based software consists of finite number of modules called web pages. The control is transferred among the web pages through hyper links according to Markov process. The software fails or reaches its final state successfully and/or moves to another state and finally enters into the terminal state. The reliability of web based software may be defined as the probability of entering of web based software into a terminal state successfully.
