CDW Technology Self-Assessment Tool Available for Small Businesses.

New Online Tool Based on CDW's Business Rearview Mirror Survey Helps Small Businesses Compare Their Information Technology Strategies and Use with Businesses Nationwide

VERNON HILLS, Ill. -- CDW Corporation (NASDAQ:CDWC), a leading provider of technology products and services to business, government and education, today published its online Small Business Technology Assessment Tool, which allows small business owners and information technology (IT) managers to compare their companies with peers nationally on key aspects of IT strategy and management. Users receive instant scores presented alongside national results of CDW's Business Rearview Mirror Survey, which was first reported in August.

CDW's Business Rearview Mirror Survey and Report, based on a July 2007 survey of 152 mid-size business leaders who have successfully grown their firms from small businesses, is designed to share lessons learned from their early growth with current small business owners. Key findings of CDW's Business Rearview Mirror Survey Report included:

* Employee recruitment/retention and managing IT are top small-business challenges. Given 14 choices and a write-in opportunity, 52 percent of the successful entrepreneurs responding selected recruiting/retention, followed by 38 percent selecting "managing IT to our best advantage."

* Small businesses that view technology as a strategic or competitive investment tend to grow faster than their counterparts - 61 percent of those holding that view reported double-digit average annual growth over the past 5 years, compared to 43 percent of those who "spent just enough" to ensure employees can do their jobs.

* A business owner's understanding of technology's usefulness correlates positively to the company's growth - 73 percent of those rating themselves "total geeks" reported double-digit average annual growth over the past 5 years, and 48 percent of them said their companies reached 100 employees within their first 5 years, compared to 33 percent of all survey respondents.

* Almost all small-business owners are very involved in IT decisions, but leaders of the highest-growth small businesses (greater than 20 percent average annual growth) are more likely to rely on others to manage the IT details; 49 percent of them had dedicated IT staff at the 100-employee milestone, compared to 24 percent of all responders.

* Successful business principals offered lessons learned from their growth experiences:

         -- Integrate IT into business strategy early - 18 percent of
            respondents said that failure to do so had been their
            biggest IT mistake over the years

         -- Understand as much as you can about technology and how it
            can serve your business - 65 percent of responders agreed
            or strongly agreed that IT was a key contributor to their
            growth beyond 100 employees

         -- Capture the full advantage of technology you acquire,
            through high-return applications and employee training -
            21 percent of respondents said that IT in production or
            project management had the most impact on their bottom
            line, and 18 percent pointed to supply chain management

CDW's Small Business Technology Assessment Tool is based on the CDW Business Rearview Mirror Survey and compares small business users with a national population of their peers on key attributes such as:

* Size, longevity and growth rate

* Growth challenges

* Business/IT strategy, investment and key applications

* Owner involvement and knowledge of IT

* IT staffing and outsourcing strategies

"CDW's Small Business Technology Assessment Tool enables business owners and their IT staff to understand how they might improve their competitiveness and growth," said Mark Gambill, vice president of marketing at CDW. "We know that small-business owners are interested in learning from each other through surveys, success stories and benchmarking. CDW's online evaluation tool encourages that by helping small businesses look at IT from a value-add perspective."

The Small Business Technology Assessment Tool is online at ConduIT@CDW (www.cdwconduit.com), CDW's online resource for small businesses and the IT professionals serving them.
