Without quick and integrated feedback from continuous monitoring, it becomes really difficult to figure out what kind of problems can occur in case of incidents and what potential root causes need to be eliminated. The figure shows the task classification quadrant by Charles Perrow. The quadrant is based on two dimensions, Tasks Analyzability and Task Variability. Task Analyzability is defined as the extent to which, when an exception is encountered, there are known analytical methods for dealing with it. Task Variability is defined by the number of exceptions to standard procedures encouraged in the application of a given technology. A value stream analysis can help to determine where processes can be improved and what are the tasks with high analyzability and low variability.
