One common procedure is to try the package on a set of randomly chosen problems. We suppose that whenever a program encounters an error, a system failure results. At this point the software is inspected to determine and remove the error responsible for the failure. This goes on for some time and two problems of interest are 1) to estimate the error rate of the software at a given time t, and 2) to develop a stopping rule for determining when to discontinue the testing and declare that the software is ready for use. In this paper, a model for the above is proposed as an estimation and stopping rule procedure.

Our research was motivated by the fact that although there are practical situations in which this assumption could be easily violated, much of the published literature on software reliability modeling does not seriously address this issue.

The models discussed fall into two categories, the data domain and the time domain. Besides tracing the historical development of the various models their advantages and disadvantages are analyzed. This includes models based on discrete as weil as continuous probability distributions. How well a given model performs its purpose in a specific economic environment will determine the usefulness of the model. Each of the models is examined with actual data as to the applicability of the error fmding process.

In this paper we present an overview of the key modeling approaches, provide a critical analysis of the underlying assumptions, and assess the limitations and applicability of these models during the software development cycle. We also propose a step-by-step procedure for fitting a model and illustrate it via an analysis of failure data from a mediumsized real-time command and control software system.
