This document provides an overview of WHO Transformation implementation as of end 2020. It complements the report on "Transforming for enhanced country impact" submitted to the 148th session of the Executive Board (EB). Our Transformation journey has had four major phases, beginning in July 2017 when Director-General Tedros took office and launched a period of deep listening and engagement with all staff and all major offices. In February 2018, the Global Policy Group kicked off phase two, leading our work to finalize the Thirteenth General Programme of Work 2019-2023 (GPW13), redesign 13 of our core processes as best-in-class", develop our new 3-level operating model and co-create with all staff a set of core values to guide our ways of working. On 6 March 2019, the Director-General and Regional Directors initiated the third phase, which included aligning our major office structures and developing options for a more fit-for-purpose country presence. The fourth phase –implementation and continuous improvement – began in January 2020, with an initial focus on consolidating our changes and then expanding to monitoring, learning and continuous improvement.
