Kano’s idea of kata where a way to show, educate, explain and understand the basic principles of a technique, and then use this understanding and develop it through randori. Then kata is a basic education method for teaching and breaking down the techniques, but not an advanced metod to learn judo. Because then he said randori is the only way to property learn the principle of maximum efficiency and minimum effort, seiryoku zenyo.
The traditional kata is a fixed form for education a specific topic in the field of judo, you can create your own traditional kata with fixed movements and techniques, but it would always be a fixed form therefore is the traditional kata not developable, and the transfer of knowledge is limited to higher forms of katas like situational and creative, but also for randori.
The next form of kata, is the situational kata this method of learning kata is a way for athletes to learn patterns of predefined movements where the athletes can train on the fundamental movements of their family of techniques. This could be part of development of a technical strategy that later can be used in special situations in randori.
The last method is creative kata, where the athletes extend their ‘family of techniques’ with other reactions to their first technique this leads to a continuously movement form situations to situations but when every situation is based on the scenario-based learning model specific for judo.
