In a business situation, bylaws are drafted by a corporation's
founders or directors under the authority of its Charter or Articles
of Incorporation. Bylaws widely vary from organization to
organization, but generally cover topics such as how directors are
elected, how meetings of directors (and in the case of a business,
shareholders) are conducted, and what officers the organization will
have and a description of their duties.
Bylaws generally can be amended by an organization's Board of Directors.
