Predicting Software Performance - Software I

摘要

Simple and robust model section methods are presented for software. These models allow forward projection of failure (defect) rates based on collection of a limited amount of early change control data during the software development process. Naturally, model selection is simpler when more data is available. But here, the focus is on “early model projection” because financial and temporal constraints often limit the amount of resources available for more complete collection of software performance and reliability data. If a maximum in the defect rate occurs at time t = tmax into the software development cycle, then key model selection and refinement times occur at t = 2tmax and 3tmax.
