Mae’n bwysig nodi hefyd bod adroddiad Estyn yn cyd-fynd ag Adroddiad Gwelliant Blynyddol diweddar Swyddfa Archwilio Cymru 2011/12 a welodd fod “problemau diwylliannol, problemau perfformiad a phroblemau arweinyddiaeth hirdymor, yn ogystal â gallu corfforaethol cyfyngedig wedi arwain at anghysondebau a gwendidau yn null y cyngor o gynllunio, trefnu a chyflawni gwasanaethau gwell ar gyfer ei ddinasyddion”.
It is also important to note that the Estyn report sits alongside the WAO’s recent Annual Improvement Report for 2011/12 which found "long-standing cultural, performance and leadership problems, coupled with limited corporate capacity, have led to inconsistencies and weaknesses in how the council plans, organises and delivers better services for its citizens".
