Effectiveness vs efficiency

In the popular book on business management, Effective Executive (Drucker, 1967), the author states:

“Efficiency is doing things right; effectiveness is doing the right things.”

This statement highlights the point that businesses often spend too much time incrementally improving an existing way of working. This can be less effective when compared to taking a step back and reviewing whether there is a more radical change that could give substantially better results.

Although the author’s text is aimed at business managers, the principle is useful to consider when developing software and optimizing graphics applications.
