How processes of PABR are documented depends on each project and cannot be determined in a general way. Researchers are advised to put documentation measures in place that help to store and translate processes and outcomes for those contexts in which she wants the project to proliferate. Documentation should be intertwined with moments of presentation and of gathering research material. Each project should develop a documentation method appropriate to the project, which may consist of several forms of documentation. Performances can be documented by video recordings, whereas collections, archives and media artefacts may become their own documentation. However, the collective activities are fleeting and perceived differently by each participant. The same event can be evaluated differently from the outside than from the perspectives of the performing participants. For comparison and evaluation purposes, these different experiences need to be represented in some form: collective writing, questionnaires, drawings, transcriptions of discussions or interviews, formal responses, and so on.
