Mae angen hyblygrwydd a dyfeisgarwch i ddelio ag argyfyngau.  Nid yw’r ymgysylltu ledled y DU wedi bod yn ddigon dibynadwy na rheolaidd, ac mae wedi amlygu'r gwendid yn y trefniadau rhynglywodraethol sydd â'r bwriad o gynnal Undeb datganoledig.  Ond mae'n bwysig cydnabod y cafwyd enghreifftiau nodedig o gydweithio.  Cynhaliwyd 17 o gyfarfodydd COBR (M) a fynychwyd gan Weinidogion y llywodraethau datganoledig.  Mae Canghellor Dugiaeth Caerhirfryn wedi cynnull cyfarfodydd ad hoc rhwng y pedair gwlad i rannu profiad a mewnwelediad wrth ymateb i'r pandemig, a chafwyd cyfarfodydd amlach rhwng pedwar Gweinidog Iechyd y DU.
Crises require flexibility and inventiveness. Engagement across the UK has not been reliable or regular enough, and has exposed the weakness in the inter-governmental arrangements which are intended to sustain a devolved Union. But it is important to recognise that there have been notable examples of working together. There have been 17 meetings of COBR (M) attended by Ministers of the devolved governments. The Chancellor of the Duchy of Lancaster has convened ad hoc four nations meetings to share experience and insights on the response to the pandemic, and there have been more frequent meetings of the four UK Health Ministers.
