  1. Human Factors for CPRS Melissa Eggink Jennifer Wagner August 2012

  2. What is “human factors”? Poll Question Ergonomics- door knobs and chairs Common sense Usability Optimization of processes and systems for the humans that work inside of them

  3. Objectives • Understand how Human Factors principles improve usability and reduce the probability of human error • View examples of tools "before" and "after" the application of HFE concepts • Use multi-media to demonstrate concepts like "Usability"   • Use that knowledge to discuss ways to make CPRS tools more intuitive for users

  4. Poll Results

  5. Admission Orders Medical Observation

  6. What time will the medication be administered to your patient? A) 9:00 AM B) 5:00 PM C) Now D) Both A) and B) E) It won’t/ never

  7. Outline • Demonstration • Usability principles with examples • Q&A time

  8. PRINCIPLE Show users where they are in the system

  9. PRINCIPLE Be consistent

  10. Is the shape of the door handle consistent with the wording?

  11. Poll Results

  12. PRINCIPLE Consider users’ mental models

  13. Is: 3 2 1 G consistent with users’ mental models?

  14. Video

  15. What changed? Poll Question Coffee mug The side on which the woman held the phone Color of kitchen tile Picture on the wall The type of chair in which the man was sitting Some combination of the above

  16. PRINCIPLE Be aware of conventions or standards

  17. Poll Results

  19. PRINCIPLE Provide meaningful feedback

  20. What should the nurse do differently to avoid receiving this error message in the future?

  21. PRINCIPLE Provide info when and as it is needed

  22. PRINCIPLE Use simple/ natural dialogue

  23. PRINCIPLE Minimize need to rely on memory

  24. Video

  25. PRINCIPLE Use the system to stop errors before they happen

  26. PRINCIPLE Give users an obvious way out

  27. How does a user log-out?

  28. PRINCIPLE Make important functions obvious

  29. Is it easy to pull out the information that you need?

  30. PRINCIPLE Create a clear visual hierarchy

  31. Would the average user know they cannot type in this boilerplate?

  32. Where can I go for more? • See handout for references • Within VHA: • MidWest Mountain Veterans Engineering Resource Center Request assistance: http://go.usa.gov/RVv • VA IDEA • OIA Human Factors • OIA training • hi2 curriculum • Search ‘usability’ in TMS

  33. Ask the Presenter

  34. DO NOT DISPLAY

  35. Test steps: • Identify critical goals of product/tool/application • Define typical user • Conduct critical tasks • Identify task issues/general usability issues • Compile analysis/make changes to improve
