Most of the comments have questioned the "cost" of adding 2 ADs to the lucky number 13. However, there are a other large numbers to consider. For example 26 and 24 - the number of WGs in the transport and Internet areas, respectively. I have never seen a senior manager in a commercial enterprise to whom 26 subordinates, each responsible for completely distinct disciplines, directly report. Decreasing the number of WGs per area to a number that can be reasonably managed and technically lead by the AD is one of the advantages of the proposal. And this will still leave a manageable 15 members in the IESG. Y(J)S _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
