In establishing a pay for performance model, it is important that Namibia first ensure they have reliable data as to the current inefficiencies in their HIV/AIDS monitoring and treatment system, otherwise they risk setting performance targets that are too easy to meet, much like the UK did.  A thorough study of how frequently HIV testing and treatment is done must be performed before targets can be realistically set.
