Reliability Measurement of Square Model to Develop IVR Software

Square model is a software process model to develop Interactive Voice Response (IVR) software, used in call center industry. In this article, we measured the reliability of Square Model in the presence of covariate information. For this, we derived a failure intensity function which is used to measure the reliability of model using fix number of calls, failure intensity parameter value, failures / CPU hour and mean failures observed empirically for all components to estimate failure intensity of IVR software over various time periods when it is assumed that the software is changed after each time period and that software metrics information is available after each update.
