 In preparing and performing a routine, performers make choices about what to utter and what to do. Performers also choose how to utter what is uttered and how to do whatever it is they do. And, performers determine what to do and how to do it for every moment of the performance. These decisions, so far, concern what each performer utters and does independently of other performers, but performers usually do not make even these decisions in isolation from each other. Another aspect of these decisions requires concerted, perhaps collective, effort. Any company needs to decide where they wish to direct attention at each moment and how they will do that. Some of those decisions involve thinking about such things as how performers are situated relative to each other and to the audience in the performance space. Many decisions that determine how attention gets directed involve deciding the manner and timing of each performer's utterances in relation to the content, manner, and timing of the utterances of other performers. Similarly, to regulate the attention of audiences, companies think about how what each performer is doing relates to what the other performers are  doing.[2]  Clearly, none of these tasks, especially the ones demanding coordination among the performers, is particularly easy.
