The Lavidge survey covered managers in many departments. Engineers are a different breed altogether. True to stereotype, this survey from IEEE GlobalSpec and TREW marketing finds engineers’ favorite information sources are just-the-facts case studies, ebooks, and white papers. Speaking of stereotypes, do engineers lack social skills? I’d never say that, but the survey found 64% of engineers get information from Web research while 13% ask their colleagues. In the Lavidge study, 52% cited colleagues and 34% preferred Web sites. Just the facts.
