Kind of hate the idea they even have to give their thumbs up. What's the point of Shanahan or Lieweke?
Their point is to set direction and make things happen. Their point is to convince the board why these things need to happen and how by making them happen future outcomes will improve.
The key thing here is since the board has approved of a rebuild, a rebuild will happen. You don't pitch to the board and then not do what you pitched.
