Mistake-Proofing

What It Is Used For

  • To prevent errors from occurring or recurring.

When to Use It

  • The goal of any solution to a problem should be to mistake-proof the process so that the error cannot occur again.

Important Notes

  • There are four levels of mistake-proofing, Forced Control, Shutdown, Warning, and Sensory Alert; and two outcomes, Prevention and Detection. The best mistake-proofing solution is a Forced Control-Prevention one.
  • Forced Control and Shutdown solutions have automatic triggers so they are much superior to Warning and Sensory Alert solutions.
