Ursula Burns, who takes over this summer as chief executive of printer maker Xerox Corp. (XRX), will bring to the corner office a no-nonsense management approach she developed running the company's operations.

Her style, company watchers say, stands in contrast to the approach of her predecessor, Anne Mulcahy, who turned around Xerox by convincing a demoralized staff to trust in the company's future and revitalizing relationships with customers. Meanwhile, Burns provided the blunt appraisals needed to right the company's operations.

"Ursula is very direct. You don't have to guess where you stand with her and what her reaction is to a proposal - from that standpoint there is a marked difference," said a former Xerox executive.

On Thursday, Mulcahy said she will end her eight-year tenure as chief executive, passing the company's reins to Burns. With the promotion, Burns becomes the only African-American female chief executive among the Fortune 500's top 150 companies.

Xerox declined to make Burns or Mulcahy available for comment.

Burns, widely seen as heir-apparent since her promotion to president in 2007, was instrumental in the company's turnaround. Burns is credited with successfully negotiating with company unions to eliminate or outsource thousands of jobs in 2001.

It also was Burns who was able to bring manufacturing costs down and found ways to outsource production to more efficient alternatives.

Burns, a 50-year-old Xerox lifer, joined the company in 1980 as a mechanical engineering summer intern. She is known for her blunt directness in speech and actions, and has spoken with a deep appreciation of the company's culture that preaches "diversity, quality...and pride in the brand."

Mulcahy, on the other hand, has received praise as a "charismatic leader," who revitalized a company by cutting costs while also re-establishing customer relationships and Xerox's place as a tech leader.

"Often, what a turnaround artist will do is cut costs, and that's it," said Robert Bruner, dean of the University of Virginia's Darden School of Business. "That so often proves to be a one-way ticket to liquidation."

In contrast, he said, Mulcahy was someone "who made the tough decisions to cut costs but also energized a new perspective."

With Mulcahy staying on as board chairman, she'll still have a role in guiding her successor. The former Xerox executive said one of Mulcahy's talents is in identifying and motivating top talent.

Still, Burns faces the pressure of being judged by the success of her predecessor.

"Ursula has very big shoes to fill. Anne has been an iconic turnaround leader in both her ability to energize a dispirited organization and bring sales and marketing momentum back," Bruner said.

Both Burns and Mulcahy have received much recognition for their place in business, appearing high in any list that ranks the most powerful women. However, Mulcahy - a regular top-ten member of The Wall Street Journal's annual "Women to Watch" list - said in 2006 that she looks forward to moving beyond gender.

"I yearn for the day when...the word 'woman' is not an unofficial part of my title...for the day when there is no need nor interest in a list of most powerful women in business," Mulcahy said at the time.
