Printing
The Printing team is responsible for printing operations in the Lab, including the CUPS server and the printers.
Cluster
The Cluster team is responsible for maintaing TJ's clusters (Borg and HPC).
Advanced Computing Hardware
The Advanced Computing Hardware Team is responsible for the maintenance of hardware within the Lab used for advanced computing, including GPUs.
Understudy Coordinator
The Understudy Coordinator is responsible for leading the Understudy program. The Coordinator is responsible for primarily planning the structure and activities with the Understudy program.
Infrastructure Lead
The Infrastructure Lead is one of the Lead Sysadmins who is responsible for broadly supervising all facets of the Lab's infrastructure.
The Infrastructure Lead is also responsible for:
prioritizing work among the Sysadmins
allocating work among the teams
ensuring work is done in a timely manner
ensuring best security practices and policies in the Lab
setting abuse guidelines
spearheading automation efforts
maintaining the GitLab issue tracker 
The Infrastructure Lead provides recommendations and feedback on changes to the Lab's architecture or to substantial technical changes.
The Infrastructure Lead is NOT a person who takes on all responsibility. Instead, the Lead delegates work. authority, and responsibility to other teams and people.

Lead Sysadmins
The Lead Sysadmins make up the Sysadmin Leadership Team together with the Faculty Sponsor and are the final decision-makers in the Sysadmins. They make the final call with respect to team organization/membership, access requests, and all decisions related to the Lab.
They are appointed by the outgoing Lead Sysadmins with approval from the Faculty Sponsor.
In another sense, the Lead Sysadmins are the Presidents. They may appoint Junior Lead Sysadmins (Vice Presidents), if those people are expected to become Lead Sysadmins in the next year.
Senior Sysadmins
Senior Sysadmins are sysadmins who are seniors. By virtue of being a senior, they have no additional rights or responsibilities. Instead, by virtue of having served in the Lab for a long time, they often have the most experience in a specific area and offer a valuable perspective.
Team Structure
Lead(s)
Leads are the Directly Responsible Individuals by default on a team. They are responsible for serving as the primary point of contact with respect to the team. If there is an incident relating to their team, the Lead(s) must be the one to report it.
Leads should:
stay apprised of their team's work
have extensive knowledge of the team's functional area
supervise the work done by their team members
report on their work to the broader Sysadmin team
Apple coined the term "directly responsible individual" (DRI) to refer to the one person with whom the buck stopped on any given project. The idea is that every project is assigned a DRI who is ultimately held accountable for the success (or failure) of that project.
They likely won't be the only person working on their assigned project, but it's "up to that person to get it done or find the resources needed."
... What's most important is that they're empowered.

Deputy
The Deputy (or Deputy Lead) is a backup to to the Lead(s) and defers to their opinion. If the Lead(s) is/are not available, the Deputy should be able to temporarily take over. A Deputy is only appointed if the Sysadmin has demonstrated competence and trust that would make him/her already qualified to be a Lead.
Backup
If their is no Deputy, a team has a Backup, who would be someone that can step in for a Lead in the Lead's absence. The Backup is generally a Lead Sysadmin or a Sysadmin who has previously led that team.
Team Members
Team members are people who significantly contribute to a team's goals. Passive involvement does not mean that someone is a team member. They operate under the direction of the Team Lead.
