Nid dyblygu adolygiad John Gilbert oedd diben yr asesiad cyflym, ond ymchwilio’n ddyfnach er mwyn penderfynu pa gymorth oedd ei angen. Defnyddiwyd yr asesiad cyflym hefyd fel cyfle i edrych yn fwy eang ar feysydd gwasanaeth eraill, megis addysg, er mwyn cael gwell dealltwriaeth o'r gwelliannau oedd eu hangen.
The purpose of the rapid assessment was not to duplicate John Gilbert’s review but to drill down to determine what support was needed. The rapid assessment was also used as an opportunity to take a wider look at other service areas, such as education, to inform the understanding of the improvements required.
