Stakeholder
A person or organization that has an interest or involvement in an organization, product, service, practice, or other entity.
Impact
Ignoring a stakeholder is the fastest way to get your project cancelled.
Weinto take
We map stakeholders by Influence vs. Interest. We focus our energy on the "Key Players" (High Influence, High Interest) and "Keep Satisfied" (High Influence, Low Interest). You cannot please everyone, so please the people who can fire you.
