Donna Armstrong, who has served as sales VP for the Sage X3 line, is leaving the company. Sage announced her departure this week following its earlier statement that the letters ERP would be dropped from Sage ERP X3 because it made clients think the product was costly and inflexible. Armstrong had held the position since April 2012 and joined Sage in 2010 as director of its professional services group. Rich Spring, new to the company in April as chief revenue officer, said North American units sales of X3 are up 40 percent over last.
