SuccessFactors, a developer of business execution software, announced that it has added a fifth show to its 2010 event roster. Chicago will be the site of the new SuccessConnect 2010 addition, after selling out New York and San Francisco earlier this year.

According to the company, both the New York and San Francisco events were 70 percent larger than last year—attracting almost 1,000 attendees.

The growth, says the company, is attributed to a format change in 2009 that made the events "more intimate and accessible to give customers a better opportunity to listen learn and share on how to maximize business execution."

The show is leveraging feedback from the New York and San Francisco events to include two "birds of a feather" lunches for attendees to break down into special interest groups. The show will also debut a SuccessAwards Chicago program.
