IAOP
IAOP was born, back in 2005, out of the idea there should be an association not simply for those working in outsourcing, but also that defines outsourcing as a profession in its own right.
It was a good idea then, and though the industry and "outsourcing" have evolved into various collaborative approaches, it's a good idea now.
IAOP’s unique characteristic—core competency—is its ability to bring together this diverse, highly collaborative and passionate group of individuals and organizations from the provider, advisor and buy-side community and provide the tools, resources and connections they need to succeed.
IAOP is truly an association for the members, by the members.
