Q

Why can automation not be the solution to preventing errors?

A
  • Only solves rule-based and skill-based tasks - knowledge-based tasks requires humans
  • Processes will be less visible to users, making it harder to troubleshoot
    -Automation can lead to larger design flaws instead of simple human flaws
