> every system has exactly one bottleneck at any given point in time.
Consider this system that has 5 sequential steps with these durations:
Step 1: 10 seconds
Step 2: 5 hours
Step 3: 7 seconds
Step 4: 5 hours
Step 5: 18 seconds
It would seem that both step 2 and step 4 are both bottlenecks. Are you saying that in reality one of those 2 steps would not typically be the exact duration so one of them would be considered the actual bottleneck?
