Management decisions ...
Quite a lot of the A400M programme's problems were caused by what one could call "the old team", and Mr. Enders and his new team have had to spend a lot of time and effort clearing the stables - don't knock their glee that things seem to be going well at last.
PS. Also, don't forget the time lost through a member of the engine consortium's inability to get the software right, within certificators' parameters ...
