Stakeholder

"an individual, group, or organization, who may affect, be affected by, or perceive itself to be affected by a decision, activity, or outcome of a project" (Project Management Institute, 2013).

"any entity(individual or organization) with a legitimate interest in a system. Typical stakeholders include users, operators. organizational decision-makers, parties to agreement, regulatory bodies, developing agencies, support organizations, and society-at-large." (INCOSE 2011, INCOSE 2015)

CAI Observation: INCOSE draws distinction to those parties with a "legitimate interest" while PMI includes the term "perceive itself to be affected".  There is need for discussion on the term legitimate.  A perceived interest with a voice could be legitimized in culture.
