Former Dell executive Donna Troy, who joined Epicor as a high-profile hire, is leaving more quietly. The company said that Troy left the company as of March 12. Troy had served as EVP for the company's ERP operations for the Americas since July 2013. Last month, Epicor said that sales execution problems had hurt ERP results in the United States, with revenue from that segment dropping by 2.8 percent for the quarter for the first quarter ended December 31 over the prior year's results.
