I think you missed out some key people from your Diamond Sixty list. For instance national cancer director Mike Richards, for delivering the cancer plan and developing the cancer reform strategy. He encourages a bottom-up approach and listens to patients and staff.

And what about Janet Williamson, who leads the Cancer Services Collaborative improvement partnership team? This supports the delivery of the cancer plan and cancer reform strategy by working with local clinical teams in England.

She now leads NHS Improvement, focused on service improvement in cancer, heart disease, stroke and diagnostics.

Finally, there's Peter Homa, for early leading edge improvement. He also led Leicester Royal Infirmary's national pilot for redesigning the healthcare process, and established the National Patient Access Team, Commission for Health Improvement and the Healthcare Commission.
