The National Consulting Index (NCI) determines the strength of a national management consulting sector (MCS) relative to other countries. It was first created in 2017 following research and analysis conducted by a team at the International Council of Management Consulting Institutes (ICMCI) . This 2023 project aims to refine and strengthen the computational model for estimating an NCI, to update earlier work to estimate the size of the MCS in each country for which data are available, and to use the data to learn more about the trends and characteristics of the national consulting market for each country represented by an ICMCI Member Institutes. The goal is to produce the world’s most authoritative summary of the size and characteristics of the management consulting industry.

This paper provides an update on the NCI project and offers estimates of the MCS for many countries worldwide. The paper first outlines the project method and the derivation of the NCI. The results of the NCI research are shown in two parts. The first part shows the financial estimates (US$m) of the MCS for the countries covered by the research (quantitative data). The second part reports insights (qualitative insight) from the ICMCI Member Institutes in some countries. The paper concludes with a reflection on the NCI project and its implications for future research.

These data represent the most comprehensive publicly available estimate of the management consulting sectors worldwide.
