A stakeholder radar diagram is a simple way of visually showing stakeholder information along multiple vectors or areas of interest at once.
The radar diagram can help identify those stakeholders who are important for different aspects of the project or for the overall project success based on multiple criteria.
The radar diagram is extremely simple to create and is a standard chart option within Excel. Simply rank different stakeholder aspects on a consistent scale, select the columns, and choose the radar (also known as a spider web) chart option in Excel. Excel will then render the chart such as the one below which ranks specific stakeholders along axes of power, legitimacy, impact, interest, and support. A common scale of ranking from 1 to 5 was used for each aspect.
The results would look something like this:
Those stakeholders who are charted closer to the edge of the chart are those who are most important on that specific aspect. By looking at those stakeholders who are consistently towards the outer edge of the diagram on all criteria, you identify those stakeholders who are likely to be the most important for project success.
Because a common scale needs to be identified for all criteria being measured (such as a 1 to 5 scale in this example), care needs to be taken to ensure that the values of the scale represent a similar level of importance across all aspects being measured. Failure to do so can incorrectly elevate the importance of specific stakeholders.
I originally wrote this thinking it was something I came up with on my own. But some further research has turned up a number of others that had similar ideas.
