But there are many ways in which to interpret it.
I think the issue is worth exploring a while.
It hadn't struck me as odd: mostly, I think, because I don't deal
with companies at that level. But now that you mention it, I do find it
Part of it comes from your wording.
One president, many workers. Instead, for example:
many executives, one electrician.
Maybe they are all workers, and the role of "president" only
requires one worker.
I'm a little unclear on the role of president anyway. Many
countries don't use the term in industry. And those that do use
it do not all use it in the same way.
And there are partnerships. And boards of directors, and other
forms of team leadership. Families. Sports teams. Some.
And of course things change over time. Many presidents, many
kings, many leaders.
But in some situations we persist in our desire for "one". So it
seems to me that the key question is: why do we sometimes have
this association between a single person, even in roles that
require more work than any one person can really do?
Lust for easy answers, even if wrong?
Love of hierarchy?
Monotheism? The divine right of kings?
Over to you, Ron. All of you.

is batch pull, not continuous pull. Instead of a sprint, XP
calls it an iteration. In XP, like scrum, but not kanban, each
story has a high level estimate attached to it during release
planning, which is similar, but somewhat different from
backlog grooming in scrum.
