This book provides a detailed account of the origin, development, administration, revision and subsequent research findings on the benchmarking initiative from 1996-2016. It presents an overall assessment of the initiative's impact on major stakeholders, predictions regarding the way forward, and implications for other countries, especially in South East Asia.
