Yet another martial arts and agile/kanban/lean comparison, but a nice one (on Jeet Kune Do):
"To reach the masses, some sort of big organization (whether) domestic and foreign branch affiliation, is not necessary. To reach the growing number of students, some sort of pre-conformed set must be established as standards for the branch to follow. As a result all members will be conditioned according to the prescribed system. Many will probably end up as a prisoner of a systematized drill."
