(8)The organisation of work within the SSM implies that typically only two or several joint controllers carry out a supervisory task in relation to a supervised entity and perform the related personal data processing operations. Therefore, it is appropriate that the determination of the respective responsibilities of the joint controllers pursuant to Article 28(1) of Regulation (EU) 2018/1725 or Article 26(1) of Regulation (EU) 2016/679 takes account of which joint controllers carry out the specific supervisory task in relation to a supervised entity. This approach to determining the respective responsibilities of the joint controllers is particularly relevant in the context of providing information to the data subject, handling data subject requests and notifying the supervisory authorities of personal data breaches relating to the personal data processed by that joint controller.
