Richard P. Rumelt Quotes

A major advancement in the strategy field is the development of models where firm heterogeneity is an endogenous creation of economic actors.

For Schumpeter the most important firms are those that serve as the vehicles for action of the real drivers of the system — the innovating entrepreneurs.

This study partitions the total variance in rate of return among FTC Line of Business reporting units into industry factors (whatever their nature), time factors, factors associated with the corporate parent, and business-specific factors. Whereas Schmalensee (1985) reported that industry factors were the strongest, corporate and market share effects being extremely weak, this study distinguishes between stable and fluctuating effects and reaches markedly different conclusions. The data reveal negligible corporate effects, small stable industry effects, and very large stable business-unit effects. These results imply that the most important sources of economic rents are business-specific; industry membership is a much less important source and corporate parentage is quite unimportant.

Prior work has shown an association between diversification strategy and profitability. This paper replicates that association using more recent and complete data and goes on to investigate the sources of the association. Theoretical arguments are advanced which predict the association which will remain once the effects of varying industry profitability are removed. Empirical tests verify this prediction and permit the discrimination between the effects of industry and diversification strategy on profitability.

Then, in 1998, I had the chance to talk with Steve Jobs after he’d come back and turned Apple around. I was there to help Telecom Italia try to do a deal with Apple, but after that business was completed I couldn’t help asking a question. “Steve,” I said, “this turnaround at Apple has been impressive. But everything we know about the personal-computer business says that Apple will always have a small niche position. The network externalities are just too strong to upset the de facto “Wintel” standard. So what are you trying to do? What’s the longer-term strategy?”

Given that background, I was interested in what Steve Jobs might say about the future of Apple. His survival strategy for Apple, for all its skill and drama, was not going to propel Apple into the future. At that moment in time, Apple had less than 4 percent of the personal computer market. The de facto standard was Windows-Intel and there seemed to be no way for Apple to do more than just hang on to a tiny niche.

Some of the biggest changes have been in the process of generating business strategies—what I call “strategy work.” Around 1980, the received wisdom was to decentralize into business units, which would each generate a strategic plan. These plans were then amalgamated up the hierarchy, in some portfolio way, for senior management. That approach has all but disappeared, and we’ve seen a dramatic recentralization of strategy work.

In 1805, England had a problem. Napoléon had conquered big chunks of Europe and planned the invasion of England. But to cross the Channel, he needed to wrest control of the sea away from the English. Off the southwest coast of Spain, the French and Spanish combined fleet of thirty-three ships met the smaller British fleet of twenty-seven ships. The well-developed tactics of the day were for the two opposing fleets to each stay in line, firing broadsides at each other. But British admiral Lord Nelson had a strategic insight. He broke the British fleet into two columns and drove them at the Franco-Spanish fleet, hitting their line perpendicularly. The lead British ships took a great risk, but Nelson judged that the less-trained Franco-Spanish gunners would not be able to compensate for the heavy swell that day. At the end of the Battle of Trafalgar, the French and Spanish lost twenty-two ships, two-thirds of their fleet. The British lost none. Nelson was mortally wounded, becoming, in death, Britain’s greatest naval hero. Britain’s naval dominance was ensured and remained unsurpassed for a century and a half.

I consider myself a mainstream researcher in the field of business policy, and the ideas I want to describe in this paper concern the foundations of a theory of business strategy that is rooted in economics. But is such a paper, whatever its merits, really appropriate at a conference entitled 'Non-traditional Approaches to Policy Research'? Surprisingly, it is. The use of economic theory to model and explicate business strategy, as it is understood within the field of business policy, is distinctly non-traditional.

[In related businesses] common skill, market or resource applies to each.

The enhanced ability to obtain external funding and ... capacity to deploy capital internally to the most promising of a wide range of divisional ventures.

Back in the mid-1990s I was researching strategy in the global electronics industry. I interviewed 20 to 30 executives, CEOs, and division managers and asked fairly simple questions. Which company was the leader in their market? How did that company become the leader? What’s their own company’s strategy?

[ Diversification strategy is] a firm’s commitment to diversity per se, together with the strengths, skills or purposes that span this diversity, shown by the way in which business activities are related one to another.

A leader’s most important job is creating and constantly adjusting this strategic bridge between goals and objectives.

In summary, uncertain imitability obtains shen creation of new production functions is inherently uncertain and when either causal ambiguity or property rights in unique resources impede imitation and factor mobility.
