Advice to Senior Management

The management is in denial that something is not working, that employees are not happy, that users are mostly not satisfied, that competitors can sometimes be better etc. So my advice: Stop listening your ego, instead, open your ears and your eyes.
And you're smart, so do something about it.

note: some Business Units, and few leaders are better than the others...
