Basic Tenets of Human Error

Some basic points to keep in mind as we discuss the etiology of errors:

  • Everyone commits errors
  • Human error is generally the result of circumstances beyond the control of those committing the errors
  • Systems or processes that depend on perfect human performance are inherently flawed

There are multiple reasons that human error occurs. These include:

  • Communication failure
  • Lack of effective training
  • Memory lapse
  • Inattention
  • Poorly designed equipment
  • Exhaustion, fatigue
  • Ignorance
  • Noisy working conditions
  • Other personal and environmental factors
