Historically for me, any time I've worked with managers who either managed my team or projects I've worked on, whether they helped or harmed things depended pretty much solely on "does this person have management training/experience, and a desire to be a manager". I've worked with both engineers-turned-manager and "business" managers, and both have had ups and downs. But the tech industry's love of taking individual contributors and pushing them into management roles without any management training or even interest in managing people seems to be the failed experiment.
