Effectiveness, Stack says, is identifying and achieving the best objectives for your organization doing the right things. Efficiency is accomplishing them with the least amount of time, effort, and cost doing things right. If you're t clear on both, you're wasting your time. Stack identifies twelve practices that will enable executives to be effective and efficient, grouped into three areas where leaders spend their time, called 3T Leadership: Strategic Thinking (business), Teamwork (employees), and Tactics (self). For each practice, Stack offers advice from her twenty-five years in the trenches working with thousands of leaders globally. You'll receive scores of new ideas on how you, your team, and your organization can boost productivity.
