Tejun
The Japanese word tejun 手順 consists of two Kanji, te 手 meaning "play" and jun 順 meaning "order". In common parlance it is used for the steps of a procedure, and in both general usage and go usage is usually used for a well defined sequence of steps. In Go publications one sometimes sees it translated as order of play, sometimes as sequence.
In English, for the general sense where there is not a knowable, well defined sequence of play, the word "timing" might be used, which is occasionally seen in Japanese go literature.
The Japanese Go proverb (碁は手順なり Go wa tejun nari) says Go is the order of play.
