I wneud yr ymchwil, defnyddiwyd cronfa dystiolaeth gynhwysfawr sy’n cynnwys adolygiad manwl o bolisïau cenedlaethol, astudiaethau achos oddi wrth awdurdodau lleol; gwersi a ddysgwyd o brofiad llywodraethau eraill y Deyrnas Unedig; a thrafodaethau â nifer o randdeiliaid mewn gweithdai a gynhaliwyd ledled Cymru yn gynharach eleni.
The research was informed by a comprehensive evidence base including a detailed review of national policy, case studies from local authorities; lessons learnt from other UK administrations; and discussions with various stakeholders during workshop sessions held across Wales earlier this year.
