Reading guide

Published in 1966, The Effective Executive remains fresh and thought-provoking. Drucker on time management: executives spend enormous amounts of time on work that contributes nothing, yet few recognize it. If you cannot know yourself, at least know your time. Record and review its allocation; ruthlessly eliminate waste, cancel what should be canceled, and delegate what should be delegated. Stop keeping the organization in firefighting mode, make exceptional situations routine, and consolidate fragmented time into blocks for deep thought. Two priority rules: do not stay busy with yesterday’s tasks—abandon sunk costs and path dependence decisively—and do not let pressure set priorities. “Later” really means “never.” Finally, do one thing at a time.

Key points

  • Start by recording and reviewing how you use time.
  • Eliminate waste: cancel and delegate where appropriate.
  • Do not set priorities by pressure: later means never.
  • Do one thing at a time.
Distinct modular elements joined into a coordinated, balanced whole.

Peter Drucker’s The Effective Executive was published in 1966, yet still feels fresh and thought-provoking. Drucker on #TimeManagement #Executives spend huge amounts of time on work that contributes nothing #Yet very few recognize it #Most have no idea how their time is allocated #If you cannot know yourself #At least know your time #Record and review how you allocate it #Ruthlessly cut time-wasting activities #Cancel what should be canceled #Delegate what should be delegated #Do not keep yourself and your organization constantly firefighting and handling crises #Turn exceptions into routine management #Consolidate fragments of time for deep thought The third step in time management is finding ways to bring fragmented time together and form— #Do not stay busy with yesterday’s tasks First, do not stay busy with yesterday’s tasks. Once work begins, people tend to continue even if it has no future value. This resembles the economic concept of “sunk costs”: decisively abandon it and end the task. People also show path dependence on past success. A company may have succeeded with a product that no longer fits future market needs. Rather than always trying to sustain it, the company should concentrate on developing new products. #Do not let pressure determine priorities Second, do not prioritize by pressure. The most pressing, apparently urgent task may not be the most important. Truly important matters, such as strategic thinking about the future or turning decisions into action, may not look urgent. If pressure sets priorities, those important things get postponed. Experienced executives know that “later” really means “never.” #Do one thing at a time That is the first way to become effective: manage time well. Record your schedule, ruthlessly eliminate wasteful and low-value activities, consolidate fragmented time into uninterrupted working blocks, then follow the “first things first” principle and do one thing at a time.
