The largest issue right now in management imo is the fact that you get either knowledgeable in your field manager, that understands your needs but totally fails in the field of managing, business and negotiating with upper leadership, or you get guy that will work out some great deal for team, will be able to resolve issues and talk to the team, but is failing to understand working process behind what people under him do and that is demanding for team to meet the impossible quotas.

Companies should romance with duopoly - where there are 2 managers, one sport coach style guy, that works for improving quality of employee environment, understands their needs but yet demands results and second tech guy that overlooks work progress, helps with his knowledge and provides an ideas and workflow.
