The following activities can be undertaken to reduce the likelihood of prolonged expectation bias leading to near misses, incidents and accidents:

  • Design software that is usable and specifically highlight safety significant information.
  • Highlight where accepted procedures deviate from the normal (e.g. routing practices).
