Mistake Proofing

  3. 3. An Introduction Mistake Proofing is all around us whether we recognize it or not. The purpose of this document is to look at some of the common ways it can be deployed and examples to help begin to recognize and start to employ in our spheres. This does not seek to be the last word, but hopefully a door to seeing mistake proofing in the world around us. --Tom Curtis 2010
  4. 4. Forms of Mistake Proofing Preventing Pausing Notifying Minimizing Guiding May overlap or be used in combination
  5. 5. Preventing In some cases a mistake can be prevented. This may include use of shape or size or function. Classic examples in this space include the different size of the diesel and unleaded gas nozzles, or something that can only fit in one way. This is sometimes called poka-yoke. This form is most often associated as mistake proofing.
  6. 6. Different Size Hook Preventing
  7. 7. Inside Trunk Release Preventing
  8. 8. Protects Against Balls Preventing
  9. 9. Key Required to Adjust Preventing
  10. 10. Newspapers and no Bottles Preventing
  11. 11. No Lost Tickets Preventing
  12. 12. Helps Fight Unhappiness Preventing
  13. 13. Automatically Locks Preventing
  14. 14. No Hook Hanger Preventing
  15. 15. Pausing Pausing or delaying techniques do not fully prevent a mistake occurring, but rather force an individual or group to stop and overcome some hurdle to proceed. An example is a computer program that asks “Are you sure?” before executing a desired command. The goal is that in being forced to stop a mistake may be prevented.
  16. 16. 2 Step Process Pausing
  17. 17. Review Before Ballot Cast Pausing
  18. 18. Difficult to put in Pocket Pausing
  19. 19. Must Push Twice Pausing
  20. 20. Must Push both Buttons Pausing
  21. 21. Notifying In notifying the system or process lets us know that something needs to be addressed, but does not prevent us from continuing, like in preventing or pausing forms. For this type of proofing think of the gas light in most cars. It lets us know that a mistake will eventually be made (running out of gas), but it is up to us as to whether we heed the notice or not.
  22. 22. Gas Needed Soon Notifying
  23. 23. Entering Oncoming Lane Notifying
  24. 24. Helps Proper Setup Notifying
  25. 25. Stay Out Notifying
  26. 26. Minimizing In minimizing it is realized that there may be a mistake made, but that the damage can be controlled. Think of a machine that shuts down when it gets too hot. The machine does get hot, but does not allow the motor to burn out. There is some damage done, but the greater damage is minimized.
  27. 27. Triggers Turn Off Minimizing
  28. 28. Eventually Self Turns Off Minimizing
  29. 29. Less Likely to be left on Minimizing
  30. 30. Less Splashing Minimizing
  31. 31. Guiding Guiding or suggesting is similar to notifying, in that it does not stop the process and is a message from the process. It differs in that there is not a mistake that will happen if disregarded. An example is the please wash your hand signs for employees that you often see in public restrooms. We are protected if we heed, but are not punished automatically if we do not.
  32. 32. Friendly Restroom Reminder Guiding
  33. 33. Gentle Nudge Guiding
  34. 34. Warning of Terrain Ahead Guiding
  35. 35. Reducing Lost Cars Guiding
  36. 36. Request for Help Guiding
  37. 37. Can be seen in Case of Fire Guiding
  38. 38. Gentle Nudge Before Fueling Guiding
  39. 39. Reducing Injuries Guiding
  40. 40. Driving Tip Guiding
  41. 41. Strong Suggestion Guiding
  42. 42. Cleaning between Uses Guiding
  43. 43. Request to Refrain Guiding
