IAOP® is accepting applications through November 1, 2011 for the annual, independently-judged opt-in ranking.

Now entering its seventh year for service providers and fourth for advisors, the Global Outsourcing 100® has become an important resource to help companies make more informed purchasing decisions based on an objective methodology.

In 2011, Accenture was named the world’s best outsourcing provider for the fourth consecutive year while Alsbridge topped the list of leading advisors in the industry.

The unranked lists will be previewed at the 2012 Outsourcing World Summit, Feb. 20-22, 2012 at Walt Disney’s Contemporary Resort, Lake Buena Vista, Florida, and fully released in May 2012 in a special advertising section of FORTUNE magazine.

“Global Outsourcing 100 is being recognized as a premier listing of service providers and customers have come to depend on it for their research for exploring the outsourcing marketplace,” said IAOP Managing Director of Thought Leadership, Jagdish Dalal, COP. “Providers have looked at the list and created their own strategic action plan to improve their positioning for the future list. IAOP believes that this leads to a healthier and a more competitive outsourcing marketplace.”

Companies will be judged using an objective methodology that examines 18 criteria, including size and growth, customer references, organizational competencies and management capabilities.

Companies can submit applications for the Global Outsourcing 100 and World’s Best Outsourcing Advisors via an online application form and do not have to be IAOP members to apply. The deadline for fully completed applications is Nov. 1, 2011.
