Nokia's execution on a corporate level did not improve since Elop took office (might not be Elop's fault as changes in organizations take time, regrettably), however execution on the executive level (transition away from Symbian) is horrendous as the profit warnings show. And this is Elop's responsibility. If Elop is able to fix Nokia's execution problem, Nokia might be very well doing the wrong things very well. Not a good perspective from Nokia's point of view.
