Quick tips
Use a power/interest grid to plot stakeholders.Update the stakeholder map regularly as the project evolves.
Identify both positive and negative stakeholders.Customise communication plans for different stakeholder groups.
Engage team members in the mapping process for a broader view.Common pitfalls
Missing less apparent stakeholders.Not reassessing stakeholder positions over time.
Ignoring low-power stakeholders.Overlooking the need for individual engagement strategies.
Assuming stakeholders’ interests do not change.Project success can be achieved by carefully identifying and communicating with key project stakeholders. The concept of a stakeholder map can be explained as the graphical representation of project stakeholders. The process to be performed for conducting a stakeholder mapping analysis is very crucial for the project success. When starting with a new project, the first phase in stakeholder mapping analysis is to conduct a stakeholder identification process. The stakeholder identification process in a project involves categorising the identified stakeholders based on their impact on the project and their level of influence in the project.
