The RASCI model is a framework to identify external project stakeholders, and to help keeping those people involved in the appropriate fashion. In an organization like mine, global projects are handled by regional staff that cooperate. Each team member is embedded in his own local context, so it’s very hard for the project coordinator to have a complete overview of the project’s stakeholders.
Asking my colleagues to give me an overview of their external stakeholders as per the RASCI model should help identifying and addressing potential issues before they become problems.
