This is a known risk that can be managed with systems, processes, validations, procedures, supervision, management and other internal controls that can be used to reduce or eliminate human error. The following are common examples of human error.
Not paying attention
Failure to notice change
Divided attention
Overfocus on one aspect of a task
Poor system usability
Poor procedure design
Error prone tools
Error prone processes
Misinterpreting sensory information
Misjudging distances
Mishearing things
Misidentifying odors
Using vague language
Noise interference
Using jargon others don’t understand
Lack of feedback
Skipping steps
Performing steps out of order
Deliberately ignoring procedures
Poor decisions
Not making a decision as required
Doing nothing when action is required
Acting when no action is required
Acting before the appropriate time

Failure to verify
Deliberately undermining colleagues
Refusing to follow directions
Resisting change to processes or directions
Spatial disorientation

Environmental hazards
Equipment malfunction
Inadequate workspace
Mental fatigue
Physical fatigue
Information overload
Lack of accountability
Ineffective leadership

Human Error & Risk

The risks associated with human error can often be reduced by developing processes and systems that are human-friendly and error tolerant. Industries related to human safety such as aviation were early pioneers of techniques to reduce human error. For example, an aircraft maintenance procedure may include a complete inventory of all tools to ensure that nothing has been left behind in a jet engine.

Human Error & Culture

Another important consideration for reducing human error is establishing an organizational culture that encourages people to openly discuss their errors. This is a major issue in fields such as medicine where there is much fear of discussing errors.

Human Error & Accountability

It is common for firms to blame problems on human error by low level employees. This is not acceptable for major problems where systems, management, validations, processes, procedures and other internal controls could have prevented the error. Techniques such as 5-whys can be used to ensure senior management and governance accountability.
