Umbrex, Tuckman Stages of Group Development (Forming-Storming-Norming-Performing)
The directory entry this score was read from. Umbrex is a consultancy network; its summary is the reference, not a primary source.
It loads no cell. It describes a condition that a shape depends on rather than a design choice for a cell, so it appears on this site as a precondition, the field on every shape page, and not as a score.
Describes a developmental sequence rather than a cell design choice, so it is scored as a precondition though outside the Leadership and Culture categories.
This is not a summary of the framework. Umbrex has one; the link under Sources goes there.
Nowhere on the sheet. Preconditions are held on the shape pages, where a room checks them before choosing a shape.
