(59)The resolution college's written arrangements and procedures should also include the necessary operational provisions to ensure that the college enables the resolution authorities to both coordinate their input to the supervisory college and to organise the analysis, consideration and evaluation of the input that the resolution authorities receive from the supervisory college. Written arrangements should, therefore, ideally include a process of communication between the supervisory and the resolution college, most importantly between the group-level resolution authority and the consolidating supervisor. Written arrangements should also lay down the processes to be followed within the resolution college for reaching a common understanding, in all cases where coordination is needed in practice but a joint decision is not required in accordance with Directive 2014/59/EU.
