What is performance evaluation?

As it states in its title, "a performance evaluation" is a
tool used to assess how an individual is performing in a given capacity.  It is used for
a variety of reasons.  In some organizations, it can be strongly linked to upward
professional and economic mobility.  It can also be used as a tool for professional
growth and advancement.  Some performance evaluations are geared towards making an
individual more proficient in their given field.  This can be done by being able to
identify specific goals and objectives that must be worked on by the professional.  I
think that a performance evaluation can be used in this domain in order to make an
individual able to contribute more to their given vocation.  In different realms,
performance evaluations can be used to not only reflect an individual in a particular
organization, but also an individual as a professional, as well.
