My experience agrees although proper management training/mentoring can alleviate some of the issues. However the timeline I've experienced is different: * You have a great engineer or lead who knows the project inside and out * They are promoted to management. * They still know the project inside and out plus were recently coding so they dictate how things are done technically. It works great. * They get put on a new project which they don't know inside and out. * They dictate how things should be done technically because it worked for them in the past successfully. It works horribly.
