Ers i’r Bwrdd ddechrau gweithio gyda’r awdurdod, cafwyd mwy o dryloywder, gyda cyfarfodydd pwysig yn cael eu dogfennu’n iawn a’r papurau’n cael eu dosbarthu i’r Cyngor llawn; darparwyd gwybodaeth ble nad oedd dim ar gael cyn hynny; cafwyd mwy o gysylltiad rhwng y Prif Weithredwr ac aelodau sydd wedi’u hethol; a chymorth broffesiynol gyda craffu.  Mae aelodau Panel Diogelu y Prif Swyddogion wedi’i ddiwygio ac mae AGGCC wedi nodi gwelliant yn ymateb yr awdurdod i geisiadau yr Arolygiaeth am dystiolaeth.
Since the PMB began working with the authority, there has been greater transparency, with key meetings being properly documented and papers disseminated to the full Council; provision of information where none was previously available; greater engagement of the Chief Executive with elected members; and professional support for scrutiny.  The membership of the Chief Officers’ Safeguarding Panel has been revised and CSSIW has reported improvements in the authority’s responses to the Inspectorate’s requests for evidence.
