I can't help but think that the statement below, from the CIPD's Next Gen HR - Time for change, shows a profession that has just thrown its toys out of the pram. Or if you prefer your metaphors of the footballing variety, the CIPD has just done a Zidane.
Every business gets the HR it deserves
This strikes me as both shirking responsibility for people management on the one hand and on the other, a tacit acknowledgement that HR lacks anything like a consensus around its raison d'etre. Perhaps the idea that 20 - 40% of performance is determined by the quality of people's relationships might be a start?
As for the 'insight driven' approach, haven't we been here already?
