Big is Fragile: An Attempt at Theorizing Scale

TL;DR

This paper theorizes that large capital investments are inherently fragile due to their disproportionate exposure to uncertainties, leading to higher risks of poor or negative outcomes despite economies of scale.

Contribution

It introduces the concept of fragility in big investments, highlighting the non-linear risks associated with scale and advising careful consideration of when scaling is beneficial.

Findings

Large investments are more susceptible to uncertainties.

Fragility increases with scale beyond certain thresholds.

Automatic scaling assumptions can lead to project failures.

Abstract

In this paper we characterise the propensity of big capital investments to systematically deliver poor outcomes as "fragility," a notion suggested by Nassim Taleb. A thing or system that is easily harmed by randomness is fragile. We argue that, contrary to their appearance, big capital investments break easily - i.e. deliver negative net present value - due to various sources of uncertainty that impact them during their long gestation, implementation, and operation periods. We do not refute the existence of economies of scale and scope. Instead we argue that big capital investments have a disproportionate (non-linear) exposure to uncertainties that deliver poor or negative returns above and beyond their economies of scale and scope. We further argue that to succeed, leaders of capital projects need to carefully consider where scaling pays off and where it does not. To automatically assume that "bigger is better," which is common in megaproject management, is a recipe for failure.
