Referral

As explained in BDD in Action, Second Edition

Referral is the metric measuring how effectively users introduce other people to an organization's products or services.

Referral asks whether customers introduce other people to an organization’s products or services. Within the AARRR metrics—Acquisition, Activation, Retention, Referral, and Return—it identifies a potential path to growth through customers’ recommendations. section 4.4.1

To examine referral, ask:

  • Do customers recommend the service through positive reviews or comments? section 4.4.1
  • Would a refer-a-friend program give them a reason to invite others? section 4.4.1
  • What currently prevents them from making those introductions? section 4.4.3

Business flyers

An airline team finds that business flyers have no way—and no incentive—to invite their contacts to fly with the airline. That is a referral problem: the customers cannot readily help bring others into its ecosystem. section 4.4.3
