Work Instruction Content or Sequence Changes and Operation Numbering

#1
After a work instruction has been developed and the operations have been named and numbered and frozen, and you find that process runs better in a different sequence. Do the operation numbers have to stay the same even though they will no longer, numerically, be in order?

To me logic dictates that the numbering be revised to reflect the proper sequence. I always think about a new hire coming in as a litmus test. Also - re: "runs better" - not sure if you mean quality of output or cycle time in standard work - assuring optimization for both of those factors may be important and another reason to revise the work instruction with accurate numbering.
