The entire infrastructure surrounding the programme (both men's and women's).

When asked (back in 2014) if this ad-hoc approach is a good idea, the NZRU said that "
there is more use in having our players living in the provinces and inspiring the next generation of sevens players". You can imagine how hard the NZRU board would laugh you out of the room if you suggested the All Blacks follow this nonsensical approach and train with their franchises/provinces until a week before a test match.
Then, of course, there is their reneging of the mandate that all XV's players wanting to be considered for the Olympics would have to play nothing but Sevens for the first half of 2016. This was replaced with the half-arsed to and fro between the Sevens circuit and Super Rugby.
All in all it stinks of massive hubris. I only hope that these twin failures provide the stimulus for a complete overhaul.
