Yn drydydd ‘Cydweithredu’– mae angen i wario cyffredin ac ailadroddus gael ei wneud unwaith yn unig i Gymru. Mae angen i ni drefnu ein gwariant a datblygu ffynonellau ar y cyd o arbenigedd mewn meysydd o wariant uchel megis adeiladu, gofal cymdeithasol a  ThGCh. Trwy ein ffrwd gwaith Caffael y Bwrdd Effeithlonrwydd ac Arloesi, dan arweiniad Prif Swyddog Gweithredol Cyngor Sir Ddinbych, rydym wedi comisiynu Tasglu. Mae argymhellion ac adroddiad y Tasglu ‘Prynu'n Gallach mewn Cyfnod Anoddach’ bellach yn cael eu hystyried gan sector cyhoeddus Cymru. Rwy’n falch bod ymagweddau newydd yn cael eu rhoi gerbron ac rwyf wedi gofyn i Gwerth Cymru helpu i gyflenwi a datblygu’r syniadau hyn ymhellach. Pe baem yn cynllunio a gweithio gyda’n gilydd mae gan gydweithredu cryfach y potensial i sicrhau rhyw £150m o arbedion dros y 5 mlynedd nesaf. Gwelwyd bod safoni ein manylebau a dileu amrywiadau o eitemau cyffredin yn lleihau cost a rhyddhau arbedion.
Thirdly ‘Collaboration’- common and repetitive spend needs to be carried out once for Wales. We need to organise our expenditure and develop collective sources of expertise in high spend areas such as construction, social care, and ICT. Through our E&IB Procurement workstream, led by the CEO of Denbighshire Council, we commissioned a Taskforce. Its recommendations and report ‘Buying Smarter in Tougher Times’ is now being considered by the Welsh public sector. I am pleased that new approaches are being put forward and I have asked Value Wales to help deliver and develop these ideas further. Stronger collaboration has the potential to realise some £150m of savings over the next 5 years if we plan and work together. Standardising our specifications and removing variation from common items has been shown to take out cost and release savings.
