Imodeli ye-Rapid prototype, eyaziwa nangokuthi imodeli ye-prototype, ingenye indlela yemodeli ekhuphukayo. Kuwukwakha i-prototype ngaphambi kokuthuthukisa uhlelo lwangempela, futhi kancane kancane uqedele ukuthuthukiswa kwesistimu yonke ngesisekelo se-prototype. Isibonelo, uma ikhasimende lidinga isofthiwe ye-ATM, lingakwazi kuqala ukuklama isofthiwe yesibonelo ehlanganisa kuphela ukuswayipha ikhadi, ukutholwa kwephasiwedi, ukufakwa kwedatha nokuphrinta ibhili ukuze linikeze ikhasimende, futhi akubandakanyi ukucutshungulwa kwenethiwekhi nokufinyelela kusizindalwazi, isimo esiphuthumayo sedatha. , ukuphatha amaphutha nezinye izinsiza. Isinyathelo sokuqala sokwenza i-prototyping ngokushesha siwukwakha umfanekiso osheshayo ovumela ikhasimende noma umsebenzisi wesikhathi esizayo ukuthi axhumane nesistimu, futhi umsebenzisi noma ikhasimende lihlola i-prototype ukuze liqhubeke licwengisise izidingo zesofthiwe ezothuthukiswa. Ngokulungisa kancane kancane i-prototype ukuze ihlangabezane nezidingo zekhasimende, unjiniyela angakwazi ukunquma ukuthi ziyini izidingo zangempela zekhasimende; Isinyathelo sesibili siwukwakhela esinyathelweni sokuqala sokuthuthukisa umkhiqizo wesoftware owaneliswa yikhasimende.
