The true nature of bottom up

From a great comment by Bennet Simonton on a great post by David Tebbutt

Bottom-up does not mean that the boss is not in charge and fully responsible/accountable for outcomes. It only means that the boss does not misuse authority, but concentrates on helping employees to become self-directed and self-controlled since in that state they unleash their full potential of creativity, innovation, productivity, motivation, and commitment on their work.

In bottom-up, the boss provides the highest quality support to employees so that they can excel in performing their work. That support includes discipline as well as training, tools, parts, direction, policies, procedures, information, etc. Bottom-up is not some sort of touchy feely approach to managing people.
