1. ServiceNow Product Documentation - Roles in Problem Management:
The documentation explicitly defines the responsibilities for Problem Management roles. It states that the problemcoordinator [snproblemmanagement.problemcoordinator] "Can manage all problems and problem tasks." The problemadmin [snproblemmanagement.problemadmin] "Has access to all Problem Management features and capabilities
" which includes the coordinator's permissions. This confirms these two roles are responsible for managing the problem
including communications. The problemtaskanalyst is limited to tasks. (ServiceNow Product Documentation
Quebec Release
"Roles in Problem Management").
2. ServiceNow Product Documentation - Problem Management process flow:
The documented process flow for Problem Management shows that communicating a workaround is a key step in the "Diagnose" phase
and communicating a fix is part of the "Resolve and Close" phase. These actions are performed by the user managing the problem
which is the problemcoordinator or problemadmin. (ServiceNow Product Documentation
Utah Release
"Problem Management state model and process flows").
