Organizational Mission in health care

Explain, in your own words, what the terms mission, vision, goals, and
values mean from an organizational standpoint.  What is the practical
purpose of a statement of organizational values?  Under what
circumstances should an organization consider changing these, if at
all?  How do they contribute to the strategic direction of an
organization?  If you were a department manager, how would you implement
and sustain these in your organization?  Support your primary response
with at least one scholarly source. Provide in-text citations and
complete references for all sources used. Format your post according to
APA style.
