art of war logoIn the 'Art of War', General Sun Tzu recommended a strategic method to win that rarely required actual war.
The literally unbeatable samurai, Miyamoto Musashi, wrote the 'Book of Five Rings', a classic book about his strategy that is still used by executives and martial artists. This site is about these books.

Book of 5 Rings - Ground Book

The ground book () describes the whole book itself and the key points of Musashi's school of martial arts.

Japanese carpenter's tools of Musashi's era Japanese carpenter's tools of Musashi's era

Musashi explains that carpenters makes use of every kind of timber, even those that appear useless.  The measure carefully and maintain their tools well.  Similarly, he recommends intelligent use of resources. 

 In explaining the the Two Sword technique he describes its usefulness when facing multiple enemies.  This is an interesting and recurring theme in the book.  Musashi assumes you are going up against a numerically superior force.  This makes his ideas particularly useful if you are outnumbered. 

 Next Musashi talks about rhythm.  This means understanding cycles of growth and decline and timing generally.

Lastly he explains nine rules for studying his path.  This is one of the great parts of the book because each one could easily be made into a book itself.  If only modern business manuals condensed their knowledge this effectively.  Musashi used a very short form of expression here so each character had many implications.  Accordingly you need to think deeply about each point here.  None of them have only a superficial meaning:

 Think honestly

 Practise the martial path assiduously

 Get to know the arts

 Learn the ways of craftsmen

 Discern the cost and benefit of all things

 Develop your perception

 Perceive the things not visible to the eye

 Pay attention, even to small matters

 Don't do useless things
