“…[D]esign must deliver results. Designers must also accept that if they don’t, they’re not actually designing well; in technology, at least, the subjective artistry of design is mirrored by the objective finality of use data. A “great” design which produces bad outcomes —low engagement, little utility, few downloads, indifference on the part of the target market— should be regarded as a failure.”
