"Tail-splitting" is a new technique to identify defect prone modules by enhancing the focus of the Pareto distribution by a development process factor. The simple yet powerful influence of a varying tail membership as a function of development process phases is captured by the tail-split-string which tags each module. The case studies on an operating systems product demonstrate that the...
In software products, often the failure rate decreases after installation, eventually reaching a steady state. The time it takes for a product to reach its steady state reliability depends on different product parameters. In this paper we propose a new metric for software products called stabilization time which is the time taken after installation for the reliability of the product to stabilize....
The benefits that a software organization obtains from estimates of product quality are dependent upon how early in the product cycle that these estimates are available. Early estimation of software quality can help organizations make informed decisions about corrective actions. To provide such early estimates we present an empirical case study of two large scale commercial operating systems, Windows...
The traditional software reliability models aim to describe the temporal behavior of software fault-detection processes with only the fault data, but fail to incorporate some significant test-metrics data observed in software testing. In this paper we develop a useful modeling framework to assess the quantitative software reliability with time-dependent covariate as well as software-fault data. The...
