I agree that there should be a common communication management plan that is included as the SOP. This assists in the effective dissemination of information.The information distribution can be designed in compatibility to the project organization chart ensure easy flow of information. Having a common communication plan will also ensure that everyone in the company follows a designated protocol, reducing chances or error, mismanagement, receiving incorrect information, or a project team member not receiving any information at all. This will help save time, resources and also provide a scope for improvement with every team project.
