Accurate Research You Can Rely On

Every DPI employee is 100 percent committed to quality. Our quality control procedures are rigorous, because we know our clients depend on us for cutting-edge research to inform their strategic business decisions.

In the field, senior managers conduct detailed project briefings and ongoing monitoring of interviewers. Our quota controls are meticulous, and we validate at least 15 percent of interviews.

Our optimal value model includes low off-shore costs with on-shore quality and speed. Our in-house facilities, leading-edge technology and large, well-trained staff provide 24/7 capabilities that give us some of the fastest response times in the industry.

We edit open-ends as completed for consistency, we record verbatim responses from 33 percent to 100 percent of questionnaires before developing code schemes, and we provide detailed code schemes for client approval.

Our 100 percent data verification practices find and correct data-entry errors. We conduct complete table review to eliminate processing errors.

We provide data in your choice of formats (SPSS, Excel, SAS, Access, ASCII, column binary or others) and deliver it electronically or in hard copy — whichever you prefer.

DPI supplies the quality research you need in a format you can use. It’s that simple.
