By linking related Events together using "Event Origin" and "Follow Up" , you can easily keep track of interactions between your organisation and the external contacts.
Firstly, by using "Event Origin", even complex interaction can also be shown clearly
A single interaction happens between only two persons, but it can have various event types (as shown in the left side), according to the needs of the sender and receiver.
However, for complex interactions (as shown in the right side), we can have many interlocutors within it, done by different persons inside and outside our organisation, using various communication tools. In this case, if we list the events related to one person, we will only have a partial view of the conversation.
As we can see in both tables with records of detail discussions happened between VIFIB staff and its customers in subject of a new product offer, the event N°1 is the reason why the customer replied and created the event N°2. So we can say that the event N°1 is the origin of the event N°2.
So using "Event Origin" can correctly and precisely represent the relation between events.
