(4)To ensure the most effective use of resources in the execution of oversight activities, members of joint examination teams should be able to be part of several joint examination teams and to oversee multiple critical ICT third-party service providers. The number of the critical ICT third-party service providers to be assigned to a specific member of joint examination team, and overall staffing needs of the joint examination teams, should take into account the risk profile of the critical ICT third-party service providers and the envisaged level of intensity of oversight activities. That possibility to oversee multiple critical ICT third-party service providers is taken into account in the strategic multi-annual oversight plan, updated annually by the Lead Overseers to the extent necessary, and reflected into the individual annual oversight plan. To ensure the reliability of the planned and ongoing commitment of resource staffing of the joint examination teams by the nominating authorities, the Lead Overseer should consult both the Joint Oversight Network and the Oversight Forum on the strategic multi-annual oversight plan.
