How many survey questions do you recommend for a typical Diagnostic Assessment Tool?

We are living in a world of short attention spans, where buyers have less time than ever before to engage. At the same time, these buyers need comprehensive diagnostic assessments. So a balance needs to exist between the commitment we ask prospects to make, reflected in the number of discovery / survey questions, and the comprehensiveness of the discovery process.

As a rule of thumb, it is recommended that the number of survey questions, the biggest driver of prospect time commitment, be limited to:

·         Less than 10 questions for a self-service web assessment

·         Less than 20 questions / response if possible for a basic diagnostic assessment

·         Less than 50 questions / responses in almost all cases.
