Event partitioning

System context diagram for a fictitious hotel. (By convention, bidirectional flows, with arrows at both ends, are often used when a dialogue is initiated externally. For example, "booking dialogue" contains the flow "booking request", which is the initial trigger; "booking confirmation", the result, is sent back.)

Event partitioning is an easy-to-apply systems analysis technique that helps the analyst organize requirements for large systems into a collection of smaller, simpler, minimally-connected, easier-to-understand "mini systems" / use cases.
