Dimension Data saw a lot of executive turnover in 2016, with global CEO Brett Dawson, Americas CEO Mark Slaga and Americas CFO Eric Gibson departing the company. The $7.4 billion company has been pushing to move from a model of wholly operated units in each geographic region to operating globally, with only a top sales leader in each region. NTT acquired Dimension Data in 2010, and has been pushing to integrate divisions of the company with NTT or other portfolio companies.
