An integrated defect tracking model for product deployment in telecom services

This paper presents a new reliability model for the time series of failures uncovered during testing of software products. The time series can be either an S-shaped curve or a slowing exponential. The model is statistically consistent; the variance of the estimated number of failures tends to zero as the test time increases. This model can be used for managing risks in the deployment of new products that support highly reliable telecommunication services.
