The CQUIN framework potentially offered an opportunity to learn how technical design influenced outcome but due to the high degree of local experimentation and little systematic collection of key variables, it is difficult to derive lessons from this unstructured experiment about the impact and importance of different technical design factors on the effectiveness of pay-for-performance.
