To meet future healthcare challenges a broader range of values need to be included in analysis, debate and policy. Different modes of governance foreground and facilitate different values. Collaboration, the governing principle of the newly formed integrated care systems, values the contribution of diverse stakeholders in discussions and decisions, to foster creativity and produce durable solutions to complex problems. Approaches to evaluation reinforce particular values, as captured in the adage ‘what's measured is what matters’. New approaches are needed to support the collaborative aims of integrated care systems. Public value evaluation proceeds through values inquiry, establishing what is important to different stakeholders (including policy makers, healthcare staff, patients and communities) as a backdrop to understanding the effects of policies and programmes.
