Leading organization with subdivisions.

Recall the lead presentation to high-schoolers activity, our group was divided into subgroups to generate ideas and work on our own parts. This is much like having subdivisions in a large organization. So when every groups' work was on track and Pam came in as our second leader, I observed her leadership role as a leader overseeing all subdivisions.
In every subgroup that we had, there was a subgroup leader. I consider them tech-leaders, they lead their followers/peers, to work on each of their tasks. When dedicating in a certain task it is hard for the groups to consider things on a broader sense meaning on the organizational level. And I believe they do not have to. As a leader overseeing progresses from all the subdivisions, it is his/her job to make sure everything is on track and organize organizational level events to accomplish the organizational goal. By doing so, a leader gave his/her "tech" people freedom to exercise their creativity and tech-skills and focus on their tasks, while keeping the ship heading toward the right direction. What Pam did is she reminded everyone the time we had left till putting every groups work together. And when practicing the presentation all together she made sure that every group knows the order they are going and what we are going to do as a whole like yelling out "Lead" together in the end.
Consider the conceptual and interpersonal skills of a leader, I think a leader's role in an large organization with subdivisions should be like a ship captain and a butler of the organization. The leader should act like a captain, using his conceptual skills to make sure everyone on board is on the same page and guide the ship heading the right direction. The leader should act like a butler, utilizing his/her interpersonal skills to serve his followers by creating the best work environment possible allowing creativity to grow and building harmonious atmosphere among the organization.
