Richard Rumelt

He is noted for having made several key contributions to the study of business and corporate strategy. His 1974 study of diversification strategy inaugurated a stream of work on the performance implications of diversification. His 1982 paper with Steven Lippman showed how classical industrial organization results---profitability being related to concentration and to market share---could arise under perfect competition if there was uncertainty in the sources of efficiency. This result was key in the development of the "resource-based view" of strategic success. Rumelt's 1991 empirical follow-on (How Much Does Industry Matter?) showed that the most of the dispersion of profit rates in the economy was between business units rather than between industries. His 2011 book (Good Strategy/Bad Strategy) redefined strategy as a form of problem solving. It was chosen one of six finalists for the Financial Times & Goldman Sachs Business Book of the Year award for 2011. (see also more recent book Crux)
