Mike Lawrie will begin serving as president and CEO of Computer Sciences Corp. (NYSE: CSC) on Monday, the company announced today.
The Falls Church, Va.-based contractor first announced in February that Lawrie would succeed Michael Laphen in those roles by the end of March.
With the successor’s first day comes the end of an era for Laphen, who leaves the firm nearly five months after announcing his intent to retire by November 2012.
Laphen spent his entire professional career at the company and first joined its ranks in 1977.
Rodney Chase, a current board member, succeeds Laphen as chairman of the board of directors.
The company said in February that Lawrie would drive growth plans for the healthcare IT market and also focus on cybersecurity and cloud computing.
Prior to joining CSC, he served as CEO of U.K.-based financial services software firm Misys from November 2006 to January 2012 and chief executive at software firm Siebel Systems Inc. from 2004 to 2005.
He previously held senior leadership positions at IBM (NYSE: IBM), at different points leading worldwide sales and products and services distributions during his 27-year stint at that company.
