Early on, the teams were encouraged to build prototypes so that they could "bump them up against reality and discover for themselves the strengths and weaknesses of their particular approach." When Build It From Scratch shared their prototype with the group whose beepers would have to go off in the middle of the night if something went wrong with the website, they heard loud and clear about the limitations of their particular design.
Rápidamente, se animó a los equipos a construir prototipos para "enfrentar la realidad y probar por sí mismos las fortalezas y debilidades de sus enfoques particulares". Cuando Construir Desde Cero compartió su prototipo con el grupo y las alarmas sonaban a media noche si algo iba mal en el sitio web, escucharon en voz alta y clara las limitaciones de su diseño particular.
