Software reliability models ppt
WebSoftware Reliability Models-Software reliability models are statistical models which can be used to make predictions about a software system's failure rate, given the failure history of the system. -The models make assumptions about the fault discovery and removal process. These assumptions determine the form of the model and the WebSep 14, 2016 · 27. CONCLUSİONS Software reliability is a key part in software quality. Software reliability improvement is hard.
