This note explores the concept of ki, or energy. It concentrates on aikido, a Japanese martial art that channels the human body's natural energy toward balance, health, grounding, and the mental clarity required to overcome obstacles and discover new insights. Aikido is a defensively oriented martial art, designed to utilize the ki of the attack in a manner that turns that energy to the detriment of the attacker. The note discusses the six principles of aikido and applies them to business situations. It brings new perspectives on challenges and opportunities faced by businesses ranging from Dollar General to Standard and Poor's to Rodale Press, and generates insights about strategy, including purpose, mission, culture, mergers, and competition.

Iconoclasts with strongly held beliefs and a willingness to buck orthodoxy, Apple's Steve Jobs and the Chicago Bulls' Phil Jackson shared similarities in character, leadership style, and life experience that extended beyond the extraordinary successes they achieved in their chosen fields. Both came of age in the United States of the mid-20th century, a time and place characterized by Americans' growing interest in philosophical traditions outside of the Western mainstream. In their teens and twenties, both men became interested in Eastern religious practices. As young men, Jobs (who would as a teenager travel to India to study Buddhism) and Jackson (whose interest in Eastern practices earned him the nickname "The Zen Master") developed a particular affinity for the Zen tradition of Buddhism, which had a lasting influence on each man's worldview. Although Jackson and Jobs were very different leaders operating in remarkably different industries, both men's rise to the top of intensively competitive fields were influenced by their commitment to three Zen principles: nondualism, practical wisdom, and inherent enlightenment. This note gives a brief overview of the history of Zen and the philosophical framework that underpins it, then describes the potential that these three tenets hold for unlocking strategic insights.

Go (or Wei-ch'i, as it is known in China) is a centuries-old board game popular across Asia. Many have drawn parallels between military successes and the game's complex methods, in which a player encircles, isolates, and captures enemy pieces and geography, but Go also offers lessons for business. This technical note offers a basic description of Go, followed by a collection of business-strategy anecdotes punctuated by comparisons to Go strategies and quotes from Sun Tzu.
