The introduction of Agenda 2030 and the Sustainable Development Goals (SDGs) has meant that it is not ‘business as usual’ within UN agencies. Reflecting on what the introduction of the SDGs means at an operational level, a Diagnostic Instrument (DI) has been developed to provide guidance and support to International Labour Office (ILO) officials for the evaluability of SDG integration in Decent Work Country Programs (DWCP) at a country level. The Diagnostic Instrument was developed by Robert Lahey, working with the ILO’s Evaluation Office, and pilot tested in Sri Lanka and Thailand.
