Surging 60: Methodology
The two CIOZone rankings that form the basis of this article are based on the 2007 revenue and profit of publicly held software companies.
To come up with the list, we did a sort on the Security Industry Codes most relevant to software. We eliminated companies that aren't purely in software, even if software represents a big part of their business (like IBM and Sun). For simplicity's sake, we eliminated any company that isn't based in the United States.

To make the growth comparisons as fair as possible, we created one ranking for software companies that started 2007 with more than $150 million in revenue and another ranking for companies that started 2007 with between $50 million and $150 million in revenue. The rankings do not include companies that are smaller than that.

Our report uses 2007 calendar-year results, eliminating the apples-to-oranges period comparisons that would otherwise arise because of when many companies' fiscal years end. In the case of companies that don't have quarters ending in December 2007, we used the closest quarter we could find. Thus, in the case of some companies, their 2007 revenue and profit data may actually reflect results for the 12-month period ended on Nov. 30, 2007, or on Jan. 31, 2008.
We used a cut-off of Feb. 20, 2008, for our data-gathering, meaning if a company reported results after that, the results aren't reflected in the lists published here.
