Multipliers by Liz Wiseman and Greg McKeown

The authors clearly contrast effective leaders, Multipliers, with ineffective leaders, Diminishers.  On average, Multipliers get twice the capability from those they lead.  The five practices that distinguish Multipliers are:

• Attract and optimize talent throughout the organization.
• Remove fear and require best thinking.
• Extend challenges and create the belief that success will result.
• Arrive at sound decisions through rigorous debate.
• Provide resources and expect ownership and accountability.
