Eh, in my experience all situations are pretty much accounted for to be honest. The exceptions are pretty much all known, except for extreme circumstances like fires or injuries (but the system accounts for these too, as new indirect time). For instance to take your example at this scale the system will always tell you to go do something rather than wait at the pickface for a replenishment (there are lots of options for how this situation can be handled, but the job of the WMS is to capture and handle these exceptions). Less refined warehouse processes might wait, but at the level of system sophistication that these tracking systems need this is likely already engineered out. IMO in terms of being a fair measure of individual effort/performance - these systems are about as good as you can get in a warehouse and are pretty sophisticated and good at calculating the exceptions. If people disagree with using them as a management tool that’s fair enough, but IMO the calculation is much more thorough and fair than in other places where people get performance managed.
