Hidden flaws in strategy Charles Roxburgh The McKinsey Quarterly, 2003 Number 2 After nearly 40 years, the theory of business strategy is well developed and widely disseminated.

(I scored 0 out of 15 on such a test, which was one of the triggers of my interest in this field!)

We also tend to be overconfident of our own abilities.5 This is a particular problem for strategies based on assessments of core capabilities. Almost all financial institutions, for instance, believe their brands to be of "above-average" value. Related to overconfidence is the problem of overoptimism. Other than professional pessimists such as financial regulators, we all tend to be optimistic, and our forecasts tend toward the rosier end of the spectrum. The twin problems of overconfidence and overoptimism can have dangerous consequences when it comes to developing strategies, as most of them are based on estimates of what may happen—too often on unrealistically precise and overoptimistic estimates of uncertainties. One leading investment bank sensibly tested its strategy against a pessimistic scenario—the market conditions of 1994, when a downturn lasted
