The administrative clusters were formed to allow equitable access to key services between all departments. Our three departments are able to leverage the entire Metro Cluster staff.
Good for faculty, good for staff, most services have more than one person to handle things. This means more efficient service during staff absences and, well, the ability to have staff absences without the place falling apart.
Metro staff have a presence in every building. They are also available via phone, email, and most even use Skype for Business or Slack, tools available to everyone on campus.
