What is Reliability?
‘Reliability depends on the lack of unwanted, unanticipated and unexplainable variance in performance’
- Eric Hollnagel, 1993 p51
‘The major determinant of reliability in an organisation is not how greatly it values reliability or safety per se over other organisational values, but rather how greatly it disvalues the mis-specification, misestimation and misunderstanding of things; All else being equal, the more things that more members of an organisation care about mis-specifying, misestimating or misunderstanding, the higher the level of reliability that organisation can hope to attain’
- Paul Schulman 1997, Diablo Canyon Power Plant
