Diaan-Yi is Senior Partner at McKinsey & Company and currently leads the Social, Healthcare and Public Entities (SHaPE) Practice across Asia, and led its Principal investing and Infrastructure Practices in Asia.
Formerly the managing partner of McKinsey in Singapore, Diaan-Yi has worked extensively with government entities and government-linked companies in Singapore and across Asia and helps direct McKinsey’s work with sovereign-wealth funds in the region.
Diaan-Yi’s expertise includes designing and helping implement large-scale programs to drive performance transformation, accelerated digitization, and greater productivity across the public sector. She also works with sovereign wealth funds and government entities to maximize value and transform performance across their portfolio companies.
Examples of her relevant experience in macroeconomics for government entities in ASEAN include designing and supporting the implementation of an SOE Transformation Programme over multiple years, and reviewing and revamping a regional development strategy to identify initiatives to boost job creation and economic (GDP) impact.
She has also helped establish the “backward linkages” (GDP and intangible value) of companies that establish international footprints to their home country, and assessed and sized (by GDP contribution and job creation) initiatives in priority sectors for an economic agency to support post-Covid growth programs.
In addition to her public-sector work, Diaan-Yi has served clients in many industries—including financial services, telecommunications, logistics, energy, and retail—on a range of issues, such as strategy, corporate governance, and corporate finance.
Prior to joining McKinsey, Diaan-Yi worked as an investment banker at Credit Suisse First Boston in New York and London. Diaan-Yi holds an MA in Law with honors from University of Cambridge, where she was a Cambridge Commonwealth Trust Scholar and received the Dr. Cooper’s Law Studentship for academic excellence.
