Mentor & Piece

[Quizmonster]

I know what the words mean, but I'm puzzled as to how they have taken on their recent applications. It seems that nowadays, when someone who has recently achieved something is being interviewed, they are invariably asked: "Who was your mentor?" This seems to suggest that the questioner assumes there must have been just one 'advisor' who encouraged the person. If anyone asked me that question, I'd reply, "I didn't have one. Lots of people helped and encouraged me, however."
'The whole piece' now seems to mean 'the whole matter' or 'the whole organisation' etc. On the Today programme this morning, a businessman said that there would be "redundancies across the whole piece", meaning the entire insurance company in its various locations. Why 'piece' or did I mishear him?

[Peter Pedant]

You and I didnt have mentors, and did things on our own.
Remember that Napoleon said, Victoire ee has many farzzers, Defeat, ee has none.

I think that you are observing language changing before your very eyes.
