Top level Management

I read that one of the important aspects of a company is its top level management. But it’s very difficult to analyse the management as it is not a quantitative analysis but a qualitative one.Still, there may be some metrics which will give an idea about the management. What would be those?
I have watched some videos on YT and the main thing almost all videos are saying is about salary of top management and how aggressive the management is.Its easy to get details of the salary from the balance sheet.But, how to analyse the aggressiveness of the management?
I know its a vague topic and there is no any discrete answer for this question.But any input is appreciated.
Thanks
