List of all BSC Change Proposals
These pages list all Change Proposals (CP) issued since 2010. These are detailed proposals which are raised to amend CSDs and/or BSC Systems, but would not alter the BSC. They must have a clear aim, a single defined solution and contain the relevant redlined documentation changes.
