The mission of the Technical Working Group (TWG) is to make sure that the Drupal project has efficient technical policies, procedures, and standards as required to keep the "technical" side of our community operating smoothly.
The TWG's job is to ensure that the necessary policies, procedures, and standards exist to address technical concerns affecting the Drupal community. This includes items that affect all projects, such as the Drupal coding standards, Git repository usage and licensing policies, and Drupal's full-project approval process. The TWG does not necessarily author and maintain these policies itself, but merely ensures that they exist, are well maintained, and that they are successful. To do so, they appoint and empower individuals or groups within the community to care for these policies and review them as needed.
