TOPIC: What is the difference between Stakeholder matrix and Stakeholder Map?

Saw this in one of my reviewer questionnaires and was searching around for what they are, the explanations lead to pretty much the same thing - the mapping of the stakeholders in the 4 quadrant chart with their level of influence and interest. It seems the map can be more than that, but it mostly points to the 4 quadrants chart. Would anyone provide some more insight?

Hi Kristalyn,
Here is a summary of my understanding on this topic.
Stakeholder mapping is the larger topic where the PM analyzes various aspects of each stakeholder - their level of interest, influence, their preferred modes of communication, other specifics about them.

Stakeholder matrix is a specific type of stakeholder map, which can be combined with other stakeholder analysis techniques. A stakeholder map usually refers to the "Power-Interest Grid" (Power on the Y axis and Interest on the X axis. This is a method to visualize which stakeholder quadrants to focus on and which strategy to adopt for each quadrant: e.g.: do not expend too much energy on the low-power, low-interest quadrant, while focusing extra effort on the high-power and low-interest quadrant.
