That can be a loose analogy if one is using the perspective of job titles. I was emphasizing the different "cognitive activity" of each instead of job titles.

That can be a loose analogy if one is using the perspective of job titles. I was emphasizing the different "cognitive activity" of each instead of job titles. As for workers' positions/roles, that's more fluid. For example, in the small company[1], the "bookkeeper" is also doing the "accounting tasks". In this other larger company[2], the "bookkeeper" is more of a data-entry person and reports to the CPA.
