A stakeholder matrix is a diagram that helps to identify and analyze the stakeholders involved in a project or initiative. It can show the level of interest, influence, power, and attitude of each stakeholder group towards the proposed solution. It can also help to prioritize the communication and engagement strategies for different stakeholder groups12. A stakeholder matrix can help Audrey to visualize the people that are for and against the solution, as well as their relative importance and impact on the project.
