Measurement and experimentationSoftware factory improvement experiment
A software factory improvement experiment is a time-bounded change to a software delivery system that tests whether a specific intervention improves a defined outcome. It uses a baseline, a stated hypothesis, comparable measures, and a review of the evidence before the change is adopted more broadly.
Measurement and experimentationSoftware factory metrics
Software factory metrics are a defined set of measurements used to understand how an organization's software delivery system performs. They cover the movement, quality, stability, cost, and experience of work rather than reducing the factory to one activity count.
