Systems in public organizations widely suffer from poor usability. We analyzed to what extent public authorities require usability, through examining 38 call-for-tenders that were issued during a period of three months in Finland. We found six categories of usability requirements. Our conclusion is that the authorities seem to have some concern on usability. However, not a single call-for-tenders was found where usability was truly required: the usability requirements were invalid and/or not verifiable. We conclude that both more research and more guidance for defining usability requirements for practitioners are needed.
