Density is the concentration of tested judgment a person or organization has developed. Density-forming conditions are the consequential work, variation, feedback, reflection, and repeated application through which that judgment develops.
Density is not workload, tenure, hardship, pressure, or the volume of responsibility a person carries.
Optionality is the transferability and usability of that capability across roles, contexts, and future conditions. It is not simply job mobility.
An organization is a distribution of capability positions across people, roles, and critical work. One person’s self-report does not place an entire organization into a single quadrant.
