San Mateo, Calif.—Siebel Systems announced the resignation of CEO Michael Lawrie, effective immediately.
In a statement issued Wednesday, Siebel said its board of directors and Lawrie mutually agreed on his resignation. The reason for his departure was not disclosed.
Lawrie will be succeeded by George Shaheen, who was previously CEO of Andersen Consulting, now Accenture. He has served on Siebel’s board since 1995.
"The front-office market opportunity is huge—estimated at $100 billion a year—and still largely untapped," Shaheen said in a statement. "We have the people, the product leadership and the customer-delivery vision to capture it, and now we need to be unrelenting in our focus on execution."
Shaheen will continue to serve as a director of the company, and Thomas Siebel will continue to serve as chairman of the board.
