Role transfer is a usual activity in an organization, especially in a crisis situation. Role assignment and transfer regulations are important to accomplish it. This paper discusses the general role transfer problem; proposes a role specification mechanism; builds a set of terminologies for role transfer based on a revised E-CARGO (Environment-Class, Agent, Role, Group, and Object) model; and presents algorithms to validate role transfer while maintaining group viability. The contributions include formulating the problem of role transfer in a generalized form; developing a set of algorithms; and presenting a solution when group members are insufficient.
