Ownership Density Threshold

Ownership Density Threshold is the ratio of open tasks to named owners on a retainer. Below roughly 8 open items per owner, agencies get real visibility: anyone can say who is doing what this week. Above it, ownership becomes nominal, tasks sit in a queue with a name attached but no active commitment, and client deadlines slip without anyone noticing until the status call. The threshold is not a headcount problem, it is a task-granularity problem. Splitting a 40-hour deliverable into one card hides the work; splitting it into twelve cards with one owner each exposes it. Agent-first trackers make this worse before they make it better: when tasks can be created by a prompt rather than a person, volume rises faster than ownership. TaskShell syncs tasks across AI coding assistants through MCP, which is useful for solo builders but can flood a shared board with unassigned items. Audit owner-to-task ratios monthly, and treat any owner above the threshold as a capacity signal, not a performance signal.
