What is a project administrator?

The project leader takes user stories created by the product owner and works with the project team to manage the process of analyzing, scheduling and executing them.

The project leader coordinates the development team.

The project leader is sometimes called a scrum master, a team lead, or some other variation.

The project leader's primary focus is on the development of the product. This work provides feedback that's useful for defining and revising the scope of the product and for estimating the effort involved, but those are not what the project leader is directly concerned with.

In TeamForge, the project leader's main focus is the planning tree. This is the part of the interface where you define and schedule the work items and personnel needed to deliver the required features.
