startscaused

Startscause is a term used in system analysis and causal modeling to describe a specific type of causation in which the initiation of one event or process directly triggers the beginning of another. Unlike ordinary causation, which typically considers an effect following a cause, startscause emphasizes the temporal priority of the initiating event and its role in setting the stage for subsequent actions.

The term emerged in the early 2000s within the field of operational research. Researchers studying supply chain disruptions noted that certain inventory replenishment cycles began only when a preceding demand signal was activated. They coined the phrase to capture situations where the start of one activity is essential for a series of downstream events. In more formal contexts, startscause is often represented in causal diagrams by an arrow pointing from the initiating event to the subsequent event, with an annotation indicating “start prompted”.

Startscause plays a role in modeling alarm systems, where the activation of a sensor initiates an alert cascade. In software engineering, a hot‑fix deployment can instantiate a startscause relationship when the deployment event triggers a chain of automated tests and roll‑backs. In accident investigation, startscause analysis helps identify the moment an early warning system should have operated to prevent a crash.

The concept is related to, but distinct from, trigger points and threshold crossings. While a trigger point denotes a condition that must be met for an event to occur, startscause focuses on the initiation moment that guarantees subsequent events. Understanding startscause relationships aids in designing robust systems that anticipate and manage the propagation of events.
