Ranking the Americas’ top enterprise CIOs of 2015

Clare Simmons — April 2015
See our exclusive infographic: The characteristics of America’s top 20 business CIOs

Who are the most powerful CIOs across North and South America? Our annual ranking profiles the IT leaders at the continents’ top 20 companies.

Despite the tumble in global energy prices over the past year, oil and gas companies continue to dominate our list of the most influential CIOs in the Americas region for 2015.  IT leaders from the oil and gas sector occupy eight of the top 20 places, although retail champion Wal-Mart’s CIO Karenann Terrell holds the number one spot by a significant margin — one of seven female CIOs in the top 20.

The 35% of women in the list were bolstered over the past year by the high-profile appointments of Pam Parisian at AT&T, Marcy Klevorn at Ford (see November 2014 Appointments) and most recently Kathy McElligott at McKesson (see July 2015 Appointments). And showing how dramatically the gender balance has changed in recent years, six of the seven women in the Top 20 list have been appointed since 2010 and in each case their predecessor was male.

In terms of geographies, the US easily dominates the ranking, with CIOs at energy firms the only entrants from elsewhere in the Americas region.

The majority of the IT leaders featured have held their current role for several years (notably, Apple’s Niall O’Connor has been in place for a full 18 years), with only four new CIOs appointments made since last year’s table. That contrasts with a considerably higher turnover among Europe’s top CIOs (see Profiling Europe’s top 20 enterprise CIOs).
