About ISS
464x207_IAOP_2

IAOP Top 100

ISS has achieved the highest possible rating, four full stars, by the International Association of Outsourcing Professionals® (IAOP®). 
The stars are based on a thorough assessment of the top global outsourcing companies from all industries, including companies such as Accenture, Deloitte, Tata Communications and others.
 
Consistent high scores
In previous years, IAOP has ranked the companies on a global list placing ISS as the world’s no 1 outsourcing service provider in 2013 and 2014. This year, the association has changed its procedure to star ratings, and once again, ISS has achieved the highest possible acknowledgement along with a few other companies.
 
”Being named to The Global Outsourcing 100 list, and achieving 'full-star – highest rated’ in four judging categories is no easy task," said Michael Corbett, IAOP Chairman. 
 
“IAOP is pleased to recognise ISS for their excellence and achievement. The four full stars say something very significant about the consistency of ISS’ performance.”
