The Jelinski-Moranda model is a statistical model used in software reliability engineering. It is used to predict the failure rate of a software system over time. The model is based on the assumption that the failure rate of a software system follows a negative binomial distribution, which means that the number of failures follows a certain probability distribution.

One example of the Jelinski-Moranda model in action is in the development of a new software system. During the development phase, the software is tested extensively to identify and fix any bugs or defects. The Jelinski-Moranda model can be used to predict the failure rate of the software once it is released to the market. This can help the development team determine how much testing is needed and how often the software should be updated to ensure its reliability.

Another example of the Jelinski-Moranda model is in the maintenance of an existing software system. As the software is used over time, it is likely to encounter more failures. The Jelinski-Moranda model can be used to predict the failure rate of the software over time, allowing the maintenance team to plan for regular updates and maintenance to ensure the software continues to operate reliably.

Overall, the Jelinski-Moranda model is a useful tool for predicting the failure rate of a software system. It allows developers and maintenance teams to plan for the future and ensure that the software remains reliable over time. By understanding the failure rate of a software system, teams can take appropriate measures to prevent or minimize failures and ensure the continued success of the software.
