Barnwyd fod y penderfyniad i ymgysylltu â sefydliadau dilysu allanol – fel y Consultation Institute ac Opinion Research Services (ORS) – yn ystod pob un o’r tri ymgynghoriad yn synhwyrol ac yn ddefnyddiol o ran cynnig mwy o sicrwydd ynghylch prosesau’r byrddau iechyd. Nododd yr adolygiad fod rhwydweithiau’r trydydd sector yn cael eu defnyddio’n dda o ran gweithio gyda grwpiau anodd eu cyrraedd.
Decisions to engage external validation organisations - such as the Consultation Institute and Opinion Research Services (ORS) - during each of the three consultations, were seen as sensible and helpful in providing added assurance to health board processes and the review said good use was made of third sector networks in involving hard-to-reach groups.
