"We changed the dynamics of the organization," said Rodger DeRose, president and CEO of the New York-based foundation. "In general, there's a shift in the culture of nonprofits that's much more focused on the fundamentals of business."

Motivated in part by an uncertain economy, nonprofit organizations have become more results-driven by developing new ways of creating revenue, increasing employee specialization, and enhancing marketing techniques.

Changing the way an organization is run to increase efficiency and impact, a process known as capacity building, is one of the biggest trends in nonprofits, said Margaret O'Donnell, director of the American Humanics Nonprofit Certification Program.

"Organizations are interested in beefing up," O'Donnell said. "They've been looking at capacity building for two or three years, but it's really coming to a head now."

Jan Lennnon, a director of the Wisconsin Breast Cancer Showhouse in Milwaukee, said that in the past year, her organization has been more focused on leadership training and development for its board members. The way it recruits volunteers has changed; it now looks for people with specific corporate skills that can be applied to the organization's nonprofit work. For example, two women who work with advertising agencies have volunteered to help the organization with publicity.

"There's a trend to turn your focus from where you are putting your work to what you are actually achieving," said Alan Tuck, a partner at the nonprofit consulting firm Bridgespan Group that worked with Alexandra, Va.-based Communities In Schools. " That's definitely something that has more of a business feel, the way businesses measure profits. Of course, social impact is much harder to define."

Some of the changes are also due to the fact that nonprofits have been under greater scrutiny in recent years after questions were raised about the portion of donations that goes to fundraisers or telemarketers. Donors want to know that their money will be put to good use.

Harry Leibowitz, founder of World of Children, a group that honors work done for children's issues based in Columbus, Ohio, said his organization has had to carefully plan its marketing and solicit corporate donors with business proposals that detail the benefits of giving and how the money can be used.

Organizations have learned they also need a different marketing approach with individual people, who often want something in return, such as the brightly colored bracelets that have become popular since a yellow one was first worn by cyclist Lance Armstrong to help raise funds for cancer organizations. Clothes with logos, ribbons and bumper stickers are also popular products sold by nonprofits.

"This isn't something totally new, think about Girl Scout cookies" said vice president of programming at the W.K. Kellogg foundation Bob Long. "It's just that there's a new surge of interest."

At the Leukemia & Lymphoma Society in White Plains, N.Y., items including polo shirts and calendars will soon be available at the organization's e-commerce store both to increase revenue and to help the organization advertise itself, said executive vice president of revenue and marketing Richard Geswell.

DeRose, of the Crohn's & Colitis Foundation, said his organization is also selling bracelets. Since the foundation began adopting a business approach to its operations, revenue has increased dramatically, growing 30 percent in the 2005 fiscal year ending June 30, DeRose said.

Since Communities In Schools restructured, revenue has increased by 45 percent. The transformation caught the attention of others in the nonprofit community - Cardinali said in the past year 10 to 12 colleagues from other organizations have asked for advice.

"It's the smartest thing we ever did," Cardinali said.

Consultant Tuck said the number of nonprofits seeking help for their business models has grown since Bridgespan was founded in 2000. He expects that growth to continue as organizations feel pressure to keep up with the changing practices of the industry.

"It's not something that's going to be an immediate flip," Tuck said. "But, we believe that more organizations are going that way."
