If so, could you tell us what is their reasoning for just having a single customer request process time rather than both the time taken for each specific process step as well as the cumulative transaction time?


IANA’s reasoning is that it is duplicative to measure both the process steps and cumulative transaction time.  If the all the step’s SLE times are maintained then their process meets the SLE.  Unfortunately, this opens up an opportunity where, even though, the individual steps are efficiently maintained, there still could be delays in the “queues” between steps.  So for example, if you were to have a simple change request for NS records go through, the overall process could still take a months, but the SLEs of each step still could be in-line with the requirements and the transaction considered a success.


I am not sure I understand this.


If all time is accounted for somewhere, either at the customer side or at the IANA side, the described scenario could not happen. There should be no time "between steps".

Please note, since we started this process, we have been only looking at the part of the process that is in IANA’s control.  


If you include a cumulative time of the entire process, then yes there should be no “time between steps”, if there is, then the request will fail the cumulative time because you have to add the step time + the queue time. If you just measure the steps, the time differential between the time stamp at the beginning and the time stamp at the completion of the step, and there is no requirement on the time “between steps”, one request could be pulled in “between steps” for another request without consequence.


I can understand IANA not wishing to have total elapsed time in an SLE, because that includes time spent at the customer side, outside IANA's control. But since the initial and final timestamps would be available, it should be easy to know what the total time was. –Please note above, this is IANA processing time only.  The definition I have used in the document is “Cumulative IANA Processing Time”.
