Trainer
A Trainer is the person who focuses on helping others grow their skills rather than just doing the work themselves. They are the essential 'gardener' of an organization, ensuring that new talent is constantly being nurtured so the team doesn't run out of capable people.
An Orchestrator who bridges the gap between current operational output and future capacity. They manage the human pipeline by staffing the Studio and facilitating accountability, ensuring that the development of team members is treated as a core business function rather than an afterthought.
The role that maintains and grows the human pipeline: staffs the Studio, runs accountability development, and carries dual operational + developmental accountability. Its scarcity is the Trainer Paradox. (C4AIL, Whitepaper III §4.6.)
