Avoiding and Managing Errors
Error management:
• prevent errors from occurring;
• eliminate or mitigate the bad effects of errors
Two components of error management as:
(i) error containment and
(ii) error reduction.
To prevent errors from occurring,
-- to predict where they are most likely to occur and
-- then to put in place preventative measures.
Incident reporting schemes (such as MORS) do this for the industry as a whole.
Within a maintenance organisation, data on errors, incidents and accidents should be captured with a Safety Management System (SMS), which should provide mechanisms for identifying potential weak spots and error-prone activities or situations. Output from this should guide local training, company procedures, the introduction of new defences, or the
modification of existing defences.
According to Reason, error management includes measure to:
• minimise the error liability of the individual or the team;
• reduce the error vulnerability of particular tasks or task elements;
• discover, assess and then eliminate error-producing (and violation-producing)
factors within the workplace;
• diagnose organisational factors that create error-producing factors within the
individual, the team, the task or the workplace;
• enhance error detection;
• increase the error tolerance of the workplace or system;
• make latent conditions more visible to those who operate and manage the system;
• improve the organisation’s intrinsic resistance to human fallibility.
