"One does not allow the plumbers to decide the temperature, depth and timing of a bath"

This quote by Jack Gould is a metaphor for the importance of management and decision-making. It recommends that the leader of a group or organization need to be the one to make the important choices, rather than allowing the members of the group to decide on their own. The plumbing technicians in the metaphor represent the members of the group, and the temperature level, depth, and timing of the bath represent the crucial choices that require to be made. By enabling the plumbing technicians to choose these things, the leader is relinquishing their authority and responsibility. This quote emphasizes the importance of having a strong leader who is able to make the important decisions and guide the group in the best direction. It also acts as a suggestion that the leader ought to not hesitate to take control and make the decisions that are necessary for the group to be successful.
