EFS sent its managers into the field for four weeks. Each was to interview and observe ten people involved in corporate foreign exchange, including lost customers, new customers, and the customers of EFS’s competitors. The managers also reached outside the industry’s traditional boundaries to companies that did not yet use corporate foreign exchange services but that might in the future, such as Internet-based companies with a global reach like Amazon.com. They interviewed the end users of corporate foreign exchange services—the accounting and treasury departments of companies. And finally, they looked at ancillary products and services that their customers used—in particular, treasury management and pricing simulations.
