examen</figcaption> El diagrama utilitza _swimlanes_ per distingir les activitats que fa cada part. El diagrama comença quan el professor comunica als estudiants la realització d'un examen. Per indicar l'inici, s'utilitza un __punt d'inici__. En aquest punt, s'utilitza un __fork__ per indicar que a partir d'aquest moment es portarana terme diferents activitats d'una manera _concurrent_. En aquest cas, la preparació de l'examen per part del professor i l'estudi per part dels estudiants. Després s'utilitza un __join__ per indicar que quan les activitats concurrents anteriors hagen acabat, les següents activitats es realitzen d'una manera seqüencial. Aquesta estructura es torna a repetetir en el diagrama. Per últim, s'ha utilitzat un __node de desició__, per indicar que depenent d'una condició, l'activitat pot continuar per diferents camins. En l'exemple s'utilitza per indicar que sols cal generar i enviar un certificat si l'estudiant ha superat l'examen.
