Table 3.

Hierarchical representation of stakeholder groups and their responsibilities, which are the following: (1) interwoven responsibilities (self-identified responsibilities that appear to align with what is expected by others); (2) self-identified responsibilities (stand-alone) (additional self-identified responsibilities that are not reported as an expectation from others and thus not included as part of interwoven responsibilities) and (3) expected responsibilities (stand-alone) (additional responsibilities that others expect of a specific stakeholder but not identified by stakeholders themselves and thus not included as part of interwoven responsibilities) within the NZR community setting
