This chapter focuses on big data, its generation and usage, and occasional references to New information technology (NIT). NIT comprising big data, information and communication technologies and the Internet of things, is transforming every aspect of life in both industrial and developing nations. There is enormous potential for integrating NIT into the design of development evaluation, but evaluation offices have been much slower to adopt NIT than have their operations colleagues. The wide range of available NIT tools and techniques can be used to address the main challenges affecting conventional evaluation methodologies and strengthen evaluation designs. Future M&E systems are likely to be closely linked to new types of management information systems that integrate programme identification, design, management, monitoring and evaluation into a single system. Several challenges must be addressed when considering whether and how to incorporate NIT into development evaluation.
