In a 2013 survey of nearly 700 executives across a variety of industries, our firm asked respondents to rate the effectiveness of the top leaders of their companies. How many excelled at strategy? How many excelled at execution? The results are shown in the chart below. These responses are sobering: Only 16% of top leaders were rated very effective at either strategy or execution. Only 8% were very effective at both, while 63% were rated neutral or worse on at least one dimension.
