.. but keep in mind that most jets are designed to Vmo/Mmo, rather than Vne.
For those aircraft which use Vne, it is a HARD limit. There is some fat in the design and test program but, for the line pilot, one doesn't exceed Vne.
Vmo, on the other hand is able to be exceeded for specified reasons and it is not at all uncommon for Vmo to be exceeded by a small margin on descent until the pilot has time to reduce the speed a little to get back under the clacker ...
