The World Health Organization (WHO) is embarking on the most extensive administrative, managerial, and financial reforms in its 63-year history. While reform discussions started in 2010 under the title “Future Financing for the WHO,” they now encompass an organization-wide reform. The debate has expanded to include questions around the WHO’s position within today’s fragmented global health governance architecture. Reform discussions have also included deliberations about convening a multi-stakeholder forum for global health with the purpose to increase the engagement of global health-relevant actors. Ultimately, the goal is to create a WHO that is ‘fit for purpose’: a more streamlined, effective, responsive, transparent and accountable organization working to improve health outcomes.
