  A model is a simplified representation of portion of reality that hides a
system s nonessential characteristics. It provides a means for reducing
complexity as well as visualization and communication and a basis for building
it. Most models involve graphic languages during many of the software lifecycle
phases. A new model, called thinging machine (TM), has recently been developed
as an extension of the input-process-output framework. The paper focuses on
events in a TM, offering a new perspective that captures a system s dynamic
behaviors and a means of diagrammatically modeling events. The event notion is
an important factor in giving semantics to specifications and providing a
natural way to specify the interfaces and observable behavior of system
components. Specifically, five generic TM event processes are analyzed: create,
process, receive, release, and transfer. All events can be mapped (or reduced)
to the events of these five event processes
