In this session, we will explore proposed approaches for national PID support services; discuss the benefits such services could bring, including their impact on equity, efficiency, and sustainability; and assess the challenges that can hinder the implementation of these valuable initiatives. We will contrast the scale of the potential benefits they can bring, in terms of accelerated adoption, reduced integration costs, more comprehensive coverage for PID systems, improved metadata quality, time saved, equitable distribution of PID benefits, and improved openness with the challenges in establishing such a service, from making a business case to getting political buy-in. We will offer practical advice and the lessons learned from our work with several initiatives globally, and provide case studies with input from those working to establish central PID support services in their country.
