Determining the cost of a stop-test decision (software reliability)

An approach to determining the consequences of a stop-test decision that combines software reliability engineering and economic analysis is described. The approach develops a model to quantify the economic consequences associated with terminating testing at a reliability achieved with a specified number of units of test-program execution, collects data on failures and program-execution time during system test, analyzes reliability data by selecting a reliability-growth model and fitting the model to these data at several points during system test, and applies the reliability model's estimated values to the economic model to determine the optimal system-release time. The benefits-to-cost ratio of the approach is shown to be very favorable.>
