Yours is the first criticism of WPS I've read or even heard about.
there is enough on this thread alone.
WPS has not exactly been the most dynamic nor most visible leader I have ever worked under.
Had the leadership been more determined from when they walked in the door, and it would not have required a management guru to figure out where the reorganisation should have started. What happens from here on in wont be good news for many, which is rubbish given the time of the year.
For how IAG handle things, it might be worth reviewing how BA handled the absorption of BCal.
