The tech plot is close to the concept of the score, which in dramaturgy refers to a script for an action or event. The score can take the form of notes or instructions that consist of, for example, text, route maps for performers, and clarifications on the use of the performance space (Uniarts.fi 6 August 2017). Tech plots as I use them contain mainly text and are clearly written from my point of view, that of the coordinator of the performances. Originally, their use is related to managing the technical requirements of the performances, which may also distinguish them from the above definition of score.
