The generalized Jelinski-Moranda (GJ-M) model were suggested by Al turk and Alsolami  to offer several sub-models with different failurerate behaviour that can suit more different software development projects. The effectiveness of our suggestedgeneral formula is checked through a simulation study (see; Al turk and Alsolami ). In this paper the GJ-M model will be checked subjectively and objectively through fiveactual software reliability data. Three methods of estimation and four evaluation criteria will be used in our application. Both subjective and objective evaluation results show the applicability and flexibility of the suggested general formula as it can produce several sub-models with different failure rate trends.
