In 2013, I posted a Theatre Hierarchy Handout. It has been very popular because in addition to showing lines of reporting (like a tree), it also shows lines of communication. It is also arranged to demonstrate performance vs. running crew vs. build crew.
In this 2021 version, portions of the chart have been updated to reflect shifts in our industry. Projections are represented as a full design area. There are now three types of movement captain listed: Dance, Combat, and Intimacy. The chart now includes assistant designers, and some titles have been tweaked.
