Clayton M. Christensen Quotes

…I came to understand that while many of us might default to measuring our lives by summary statistics, such as number of people presided over, number of awards, or dollars accumulated in a bank, and so on, the only metrics that will truly matter to my life are the individuals whom I have been able to help, one by one, to become better people.

One quarter of Medicare beneficiaries have five or more chronic conditions, sees an average of 13 physicians each year, and fills 50 prescriptions per year.

When I have my interview with my God, our conversation will focus on the individuals whose self-esteem I was able to strengthen, whose faith I was able to reinforce, and whose discomfort I was able to assuage—a doer of good, regardless of what assignment I had. These are the metrics of that matter in measuring my life. This realization, which occurred nearly fifteen years ago, guided me every day to seek opportunities to help people in ways tailored to their individual circumstances. My happiness and my sense of worth has been immeasurably improved as a result.

If present rates of improvement continue, however, we would expect the cruising range of electric cars, for example, to intersect with the average range demanded in the mainstream market by 2015, and electric vechicle acceleration to intersect with mainstream demands by 2020.

To measure market needs, I would watch carefully what customers do, not simply listen to what they say. Watching how customers actually use a product provides much more reliable information than can be gleaned from a verbal interview or a focus group. Thus, observations indicate that auto users today require a minimum cruising range (that is, the distance that can be driven without refueling) of about 125 to 150 miles; most electric vehicles only offer a minimum cruising range of 50 to 80 miles. Similarly, drivers seem to require cars that accelerate from 0 to 60 miles per hour in less than 10 seconds (necessary primarily to merge safely into highspeed traffic from freeway entrance ramps); most electric vehicles take nearly 20 seconds to get there. And, finally, buyers in the mainstream market demand a wide array of options, but it would be impossible for electric vehicle manufacturers to offer a similar variety within the small initial unit volumes that will characterize that business. According to almost any definition of functionality used for the vertical axis of our proposed chart, the electric vehicle will be deficient compared to a gasolinepowered car.This information is not sufficient to characterize electric vehicles as disruptive, however. They will only be disruptive if we find that they are also on a trajectory of improvement that might someday make them competitive in parts of the mainstream market. The trajectories of performance improvement demanded in the market—whether measured in terms of required acceleration, cruising range, or top cruising speed—are relatively flat. This is because traffic laws impose a limit on the usefulness of ever-more-powerful cars, and demographic, economic, and geographic considerations limit the increase in commuting miles for the average driver to less than 1 percent per year. At the same time, the performance of electric vehicles is improving at a faster rate—between 2 and 4 percent per year—suggesting that sustaining technological advances might indeed carry electric vehicles from their position today, where they cannot compete in mainstream markets, to a position in the future where they might.

You can talk all you want about having a clear purpose and strategy for your life, but ultimately this means nothing if you are not investing the resources you have in a way that is consistent with your strategy. In the end, a strategy is nothing but good intentions unless it's effectively implemented.

Disruption is, at its core, a really powerful idea.

It is hard to overestimate the power of these motivators—the feelings of accomplishment and of learning, of being a key player on a team that is achieving something meaningful.
