To make chicken soup, you must have a chicken. To do a hazard analysis of a system operation (process) you need to start with a process description you can analyze.
YOU DON'T UNDERSTAND IT!
The INVESTIGATION CATALYST hazard analysis process differs from conventional processes. It provides a display of dynamic system actions and interactions on a time/actor Matrix. That format permits examination of each individual act by each element of the system for potential unintended, unexpected or unwanted behaviors and their effects on subsequent actions. The Matrix display then helps analysts develop changes that would improve future operations.
Investigators start by producing flow charts of the system operations in an actor/action matrix format. The matrix building blocks are prepared from designer or engineering or procedures inputs, or in test, startup or existing operations, by observing and documenting the actions driving the process.
|Using the Matrix|
INVESTIGATION CATALYST time/actor Matrix structures provide for the display of expected system behaviors and interactions during planned system operations. The Matrix displays can help designers and analysts work together to clarify intended operations as they evolve during the design process.
Once created, they become living documents, for long term use. For example they can be used during the investigation of new, changed, unexpected or undesired behaviors. They can be used to train or retrain process operators in the expected operation, or used to simulate possible misbehaviors to prepare operators for "surprises" they might encounter during emergency response planning. They can be used to compare planned with actual observed behaviors during system operations. They can be used to evaluate and manage changes to existing operations, and track their effects. They can be used during emergencies to guide decisions. They can be adapted to similar operations that incorporate similar interactions. In effect they offer a practical "corporate memory."
