In a nutshell, Communities of Practice
are groups of people of different
sizes who share a common concern
or have a common passion.

CoPs often emerge in the context of
existing organisations or
professional networks, in which
people are already involved in
common professional practices.

CoPs elaborate current (or develop
new) practices, through
communication, debates and
exploration of internal and external
knowledge.
