We live in an age of fundamental change, with the forces of globalisation and internationalisation generating new economic, social and educational formations. Governments, public corporations and non-government organisations all engage in innovations in order to meet the demands of this new age. This is particularly true of developing countries where the effects of poverty, unemployment, disease and political instability are even more pronounced. In the midst of all this, we find a multitude of social, health, educational and political interventions – programmes, projects, initiatives, campaigns – that are designed and implemented to address the most urgent developmental demands. These interventions are driven by a wide variety of actors within and outside of government and funded by public and private organisations as well as international foundations and agencies. The programmes in M&E have been designed for those who are tasked with the design, management, implementation, monitoring and evaluation of programmes and interventions.
