This model is structured around five streams: Formal internal communication, the traditional work of comms teams, sharing leader updates, business changes and new policies. Collaboration, encompassing all the ways that employees work together in groups to achieve outcomes. Social and cultural, helping to engage employees with the organization, and with each other. Intranet, the mainstay of internal communications and content publishing. Modern work practices, reflecting the changing ways that digital tools can help to get real work done. For each of the streams, there are three levels of maturity plus an outline of potential benefits to be gained by increasing maturity.
