The 85% Rule
We humans make mistakes, and to plan for us to be perfect is planning for disaster. Think of humans as being 85% reliable. If something needs to be done right 90% of the time, humans need help. Design tools you can use include:
-
Poka-yoke Design (parts that only fit together one way)
-
Checklists (read Atul Gawande's "Checklist Manifesto")
-
Interlocked user interfaces
-
Forms that are easy to review (for example, put all data entries in one column)
-
Process Validation
Reliability comes from design, and can't be kicked down the road to Quality and Manufacturing; design it in from the start, knowing that none of us are perfect.
