Web site owners know that selecting the right Web design vendor can be a stressful and complicated endeavor. Budgets for design services are tight, but interactive design agencies are still selective about the projects they take on. To help kick-start the vendor selection process, Forrester gathered key data from 41 firms that have significant experience designing and developing Web sites — especially in the consumer packaged goods (CPG), financial services, and retail industries. Site owners beginning the process of hiring a new interactive design agency can get critical information on these 41 agencies, which range in size from less than 20 employees to more than 750.
