Next stage of burnout research and applications.

This note introduces a holistic estimate of burnout, which can be used to extend bivariate designs such as that of Turnipseed. The "phase model" builds on but also transcends the widely accepted approach to burnout via three separate subdomains. Here, these subdomains generate eight progressively intense phases that covary regularly with differences in a wide range of variables. Also, the phase model permits diagnoses on which ameliorative designs have been based.
