This paper discusses two-dimensional software reliability measurement technologies, which describe a software reliability growth process depending on two-types of software reliability growth factors: Testing-time and testing-effort factors. From the view point of actual software failure-occurrence mechanism, it is natural to consider that a software reliability growth process depends on not only testing-time factor but also other software reliability growth factors, i.e., testing-effort factors, such as test-execution time, testing-skill of test engineers, testing-coverage. From such reason, the two-dimensional software reliability measurement technologies enable us to conduct more feasible software reliability assessment than the one-dimensional (conventional) software reliability measurement approach, in which it is assumed that the software reliability growth process depends only on testing-time. We discuss two-types of two-dimensional software reliability growth modeling approaches for feasible software reliability assessment, and conduct goodness-of-fit comparisons of our models with existing one-dimensional software reliability growth models. Finally, as one of the examples for two-dimensional software reliability analysis, we show examples of the application of our two-dimensional software reliability growth model by using actual data.
