Abstract: Assessing a collective health score of a plurality of process control systems includes automatically and periodically assessing a risk for each of the process control systems, scoring the health of each process control system within a health score scale fixed by an upper limit and a lower limit, the health score based on the assessed risk for each process control system, enabling a user to select a menu item within a navigation menu to specify higher and lower levels of integration of the health scores, and presenting a collective health score of the process control systems associated with the selected menu item.

Abstract: Negating effects of continuous introduction of risk in scoring the health of a process control system includes automatically and periodically assessing a risk for each of the process control systems, calibrating the center of a health score scale to the average risk assessments, and scoring the health of each process control system within the health score scale according to a nonlinear scale applied to the risk assessment. Introduction of a risk factor to a process control system increases the risk assessment, and elimination of a risk factor decreases the risk assessment. The same risk factor introduced to each of the of process control systems does not affect the health score of any process control system, and elimination of a risk factor has more of an effect on the health score towards the center of the health score scale than towards upper and lower limits of the health score scale.
