Dual-mode electronic survey lessons and experiences

This chapter presents a number of insights gained from a dual-mode survey of software designers recently conducted in Ireland. It describes the sampling method, pilot test procedures, response patterns, and the mechanisms engaged to authenticate participants and to filter duplicate responses. An outline is also given of how various factors with potentially beneficial affects on response rates were considered, as well as a breakdown of costs. Finally, the paper concludes with a summary of the main lessons learned.
