I won't answer your question because you just need to google "Why women are better for management" and you'll find many articles; And many major newspaper ran stories about the advantage of being a woman and manager (at least for Marissa Mayer). Women are usually granted with qualities like being able to do two things at the same time (which is good for a management position), being talkative (good for management), having empathy when necessary (good for management), being more organized...

I honestly can't list out of my mind qualities which are generally attributed to men, apart from being sharks. Please upgrade my ego if you can list any ;)
