What does it take to become more productive? Based on their recent research, the authors propose a process to help knowledge workers increase their productivity. This process involves thinking consciously about how you spend your time, deciding which tasks matter most to you and your organization, and dropping or creatively outsourcing the rest. These tasks can then be sorted into quick kills (things you can stop doing now, without any negative effects), off-load opportunities (work that can be delegated with minimal effort), and long-term redesign (work that needs to be re-conceived or restructured). Once these low-priority tasks are disposed of, the newly freed-up time can be spent focusing on more-important work.
