As a member of a project team, you implement product features according to user stories created by the product owner and planning input from the project leader.
Project team members must use their experience and judgment to estimate the effort involved in work that's been specified by the product owner and the project leader. These estimates will often lead to changes in the product scope and the project plan. In that sense, project team members are an important part of the agile planning process.
The project team members may be known as developers, programmers, engineers, individual contributors, or something else that's appopriate to the type of work being done.
In TeamForge, the project team member's main focus is the tracker. Project members can manage and track their work by observing and maintaining tracker artifacts such as user stories, defects, or tasks.
