President (corporate title)
The President is a leader of an organization, company, community, club, trade union, university or other group.
 In many organizations, it is the legally recognized highest "titled" corporate officer, ranking above the various Vice Presidents (e.g. Senior Vice President and Executive Vice President).
 The president may also be the chairperson.
 The relationship between the president and the Chief Executive Officer varies, depending on the structure of the specific organization.
 In a similar vein to the Chief Operating Officer, the title of corporate President as a separate position (as opposed to being combined with a "C-Suite" designation, such as "President and Chief Executive Officer" or "President and Chief Operating Officer") is also loosely defined.
 The powers of the president vary widely across organizations and such powers come from specific authorization in the bylaws (e.g. the president can make an "executive decision" only if the bylaws allow for it).
