- Urgent tasks vs. Important tasks
- Efficiency vs. Effectiveness
The Efficiency vs. Effectiveness distinction was first made by Peter Drucker:
Efficiency is doing things right; effectiveness is doing the right things. For manual work, efficiency was enough. In today’s world, the center of gravity has shifted from the manual worker to the “knowledge worker”. For knowledge work, effectiveness is more important than efficiency.
- Peter Drucker
Effectiveness is basically the ability to pick out and execute the tasks that are important.
The art of being wise is knowing what to overlook.
- William James
