Notes

1. “Event” is not used here in the “organized occasion” sense of the term. In other words, it is not used in the sense of a “wedding” or a “gala opening of a building” being an “event.”
2. An event is not the “carrying out” of an activity, such as performing a task, a Process, or some Systems-Engineering implementation (like implementing an Evo-Step).

3. An event must be clearly distinguishable from the non-occurrence of the event. It must be reliably observable, testable, or measurable in the real world. Consequently, events must be precisely defined – unambiguously.
However, the occurrence of an event is not the same as our Measurement of it. An event occurs whether or not it is immediately detected or measured.

4. An event usually results in some measurable change in a Status. If a specific event has occurred, then any Status associated with the event will have changed. By evaluating the relevant event Condition, the setting of a Status can be determined.

5. An “event Condition” can be defined as a Qualifier Condition – the event must have happened for the Qualifier Condition to be true.

Examples:
First Sale: Event: We make our first sale of refrigerators to the USA.
Goal [First Sale]: 99% Or-Better.

Past [Last Year, Europe, First Flight]: 98%.
First Flight: Type: Event. Description: Successful first flight <officially logged>.

6. To attempt a more detailed definition : An event is an occurrence (a set of circumstances, which include changes in Status), localized in space and time, which results from some activity, and which is significant as an indicator of progress, or as a stimulus (acts as a trigger) for other activity.

7. An event can be defined in time and space (theory of relativity), but it can be conceived of, specified, and defined, without time and space co-ordinates.
