Tasks are assigned to roles and not specific individuals. For example, the Sponsor approval task is assigned to all users who have the Sponsor role for the organization or business group that requested the business service. Likewise, the configuration tasks are assigned to all users who are Build Administrators for the organization or the business group that requested the business service. The Reboot trigger task is assigned to users who are Business Service Owners or administrators for the organization or business group that requested a change in the business service.
Individual users can claim a task to become the task owner. No other users can work on the task while it is owned by the user. If necessary, owned tasks can be released by the owner or claimed by another user.
