Drift Correction (glossary)

A resilience design principle that states that the drift of a system into a region of increasing risk should be monitored and appropriate responses should be formulated and executed – adapted from (Leveson et al. 2006)

In a resilience context according to Jackson and Ferris (2013) drift correction is a component principle of the adaptability grouping.

Discussion

This is a key resilience design principle. Although the definition above implies a gradual drift into a high risk state, it can also be interpreted to imply an immediate impending danger as was done by (Jackson 2010).
