What the research says
Should change be top-down or bottom-up?
The short answer
The research does not settle it: about half the studies support starting change close to the work, and nearly as many find it depends. In one survey, employees backed change most when middle managers started it and top managers carried it out. In an empowerment experiment, managers' sense of control rose only where they felt their own bosses backed them, though their units' measured performance also improved. More freedom for managers does not help everywhere. This is the most studied part of the Loop, and the most contested.
Based on 9 studies from the Atlas of the Middle: 1 rated high strength, 5 medium, 3 low. Designs: qualitative case (4), survey (3), experiment (1), qualitative interviews (1).
