Every corporation works best as a stand alone operational unit with its own staff and leadership
Whitmarsh is top exec at F1 Mclaren, Ron is head of Mclaren group including cars
Any chief exec worth his salt will have it in his contract that he makes the decisions and bears responsibility and reports to the board, Ron is on the board but so are his shareholders reps and MW, beyond agreeing at board level to ditch the exec there is nothing Ron or any other board member or owner do between board meetings except call emergency board meetings to pass resolutions like sacking the exec
Ron may have made mistakes but he built the team and has proven to be a success by winning things, Mclaren have never been such a joke, people make jokes comparing Mclaren to the car maker Yugo all over the web. Ron is a leader with a vision, he signed LH. Whitmarsh is not a leader or visionary just a middle manager good at helping run things not winning titles with the likes of Red Bull around
Can't blame Ron for handing over to his assistant, can't blame Ron for giving the assistant a few years breathing space, if there is no change soon and the idiocy and year 1 business student approach continues then you are right we will start to question Ron and his board
