The article profiles the business management of Equity Residential in Chicago, Illinois. The company has rolled out its integrated business information system in 2006, and virtually all of the 4,000 employees at the company's more than 600 apartment properties had learned to use it, including sales, housekeeping and maintenance staff who may not have used a computer in their jobs. Its system has incorporated property management, unit pricing and procurement functions. Equity's national education group has designed a phased approach that would teach or remediate the computer skills of employees who needed them without holding back workers who were more comfortable using a keyboard and mouse.
