Only then you'll probably be aware that sometimes it is just not a matter of being the best in business and let your technical (and management) competency excel.
It's a matter of surviving what it is being said about your work, the way you got your contract, the way you delivered your work, the way you could get the blame for issues that are not part of the scope of your work and so on. It's then that you'll have to have your executive management support (to shield you from the outer world interferences and to manage communication with that outer world).
The oddest experience I've ever had was having to work with a point of contact that was to help us execute a specific project and from minute one his intentions were to undermine the project's success. I had 20+ years of experience in the software industry, and in my innocence, I was thinking I had nothing more to learn. I was so wrong,
What if the visible face of your project start to be in the news? The news could be correct and/or incorrect; presenting sensitive data and/or confidential data (that no one knows who's disclosing). Your competition could be interested in it. Internal stakeholders could be interested in it (feeling "invaded"). Reporters could be getting it all wrong. It can get messy...
