About

Sappi

Read full description

Sappi es una plataforma que permite enviar y recibir notificaciones cuando un evento ha ocurrido. Estas notificaciones son denominadas Sappis. Un Sappi consta de: Una fotografía tomada en el momento determinado. La ubicación o sitio donde se ha tomado la fotografia. La hora en la que se tomó la fotografia. Una nota explicativa. Es una herramienta úitl para empresas que necesitan hacer seguimiento a las actividades de algunos empleados. Por ejemplo, si mi empresa es de distribución, entonces el empleado encargado de hacer la entrega, crea un sappi para su jefe cuando ésta sea efectuada.. El jefe tendrá la certeza del momento y sitio exactos en la que se realizó la entrega. Una ventaja de Sappi es que permite tener la información organizada y ordenada para ser consultada en cualquier momento. De igual forma, un usuario Sappi, puede tener varias carpetas para recibir sus Sappis y así tener una mayor coherencia y orden de su información. Por ejemplo, retomando el caso de la distribución, es posible que el dueño de la empresa requiera tener la información de las entregas organizadas por zonas, por l,oa cual, puede crear una carpeta para cada zona de distribución. Otro factor importante de los Sappis, es que estos no puedes ser modificados ni borrados. Adicionalmente, un Sappi solo puede ser consultado por el usuario que lo envía o por el usuario que lo recibe, nadie más puede ver la información de un Sappi.
