Human Error Theory
Rule Based
Errors result from the inability to recognize or
understand the situations or thecircumstances encountered.
Knowledge Based
Errors result from shortcomings in knowledge
or limitations in his/her ability to apply existing
knowledge
Skill Based (slip and lapses)
Errors of execution where a subject deviates
from the normal course of action and
performs an automatic behaviour that is
associated with another cue because is
attention deviated on another course.
Sometimes error is an action chosen but notin accordance with intention.

SLIPS and LAPSES
Generally they occur in very familiar and recurrent tasks which we
can carry out without much conscious attention
E.G.
performing an action too soon in a procedure, or leaving it too late
omitting a step or series of steps from a task
