If I understand your first paragraphs correctly, you're stating that finding a manager that has the correct balance of business and technical skills is rare to find (I have also had a PM with great technical skills but lacked business perspective). Maybe I should be spending more time in the interview process trying to analyse this balance. Regarding your proposed cure, a lot of the solutions I try to push involve increased communication (generally via utilising agile meetings, and documenting decisions via email and docs). Goals and accountability are tightly tied to this, as this becomes more significant when communication is clearer. Perhaps I will focus on this more in future projects.
