I guess I was writing from the viewpoint of a tech lead. In general I don't let management make any technical decisions so if a new idea comes up it can get implemented if the rest of the team agrees. But if someone is new he first needs to show ability first. Too many people come in, want to change to their favorite stack and just trade the current set of problems with a different set of problems.
