However, two big issues in translating this evidence into policy are cost and sustainability. Individual one-on-one consulting can be expensive – a global consulting company that we partnered with in India provided services valued at $250,000 per firm, and even using local consultants in Colombia cost about $29,000 per firm. Moreover, even if these consultants succeed in improving management, there are many reasons to worry about fade-out. Boston Consulting Group estimates that two-thirds of corporate transformations fail, as staff turns over and priorities change. Once a shock arrives, perhaps management is like a new habit that reverts to the old. © 2026 The World Bank Group,
