Teams (Products and Libraries)
Windchill solutions that include products and libraries provide two general types of teams that are used to manage user access to life-cycle-managed objects:
• A product or library team (also known as a context team) establishes the major roles used in the context and maps groups of users into the roles. The roles in a context team usually map to roles that are used in team templates or in life cycle templates.
You can use a shared team that has been created in the organization context as part or all of the context team. If you use a shared team, you may be able to add local roles and members to the team (depending on how the shared team was set up).
The product or library manager views each context team and maintains local roles and members through the Members table that is available from Products 
> or Libraries 
> .
> or Libraries > .• An object team identifies the users who participate in the team during the associated object's life cycle process.
When an object is created, the object instance has an associated object team instance whose team membership is resolved by using the roles and role mappings defined in the life cycle template, the team template, and the context team.
For additional information about resolving roles and role mappings using context teams, life cycle templates, and team templates, see Team Roles Resolution.
