Who really said it

Efficiency is doing things right; effectiveness is doing the right things

Attributed to Peter Drucker 1909–2005 · Austrian-American management consultant, educator and author
Attributed In copyright

Drucker really did draw this contrast in print: Management: Tasks, Responsibilities, Practices (Harper & Row, 1974) reads “Efficiency is concerned with doing things right. Effectiveness is doing the right things.” The tidy semicolon version everyone quotes is that same sentence with “is concerned with” compressed back to “is” — two words shorter — and no Drucker text has been documented carrying the compressed wording verbatim.

“Efficiency is concerned with doing things right” — two words longer than the popular version

The paper trail

  • 1869 and 1934 — the shape of the sentence predates Drucker. Quote Investigator ↗ records an 1869 filler item in the Harrisburg Telegraph — “There is a difference between doing a thing right, and doing the right thing” — and a 1934 Elsie Robinson column arguing that efficiency means knowing what the right thing to do is. Neither uses the word “effectiveness.”
  • May 1963 — Drucker joins the two words. His article “Managing for Business Effectiveness” ↗ ran in Harvard Business Review; Quote Investigator ↗ quotes it on the confusion between effectiveness and efficiency that stands between doing the right things and doing things right.
  • 1974 — the closest thing to the quotation. Page 45 of Management: Tasks, Responsibilities, Practices carries the sentence pair in full, verified with scans ↗. QI concludes Drucker can reasonably be credited with the efficiency-versus-effectiveness versions of 1963, 1965 and 1974.
  • The other famous version is Bennis, not Drucker. Barry Popik ↗ traces “Managers do things right; leaders do the right thing” to Warren G. Bennis and Burt Nanus’s Leaders: The Strategies for Taking Charge (1985), and QI credits Bennis for the leading-versus-managing wording in his 1997 Managing People Is Like Herding Cats.
In copyright

Management: Tasks, Responsibilities, Practices was published by Harper & Row in 1974 — some bibliographies, including Wikipedia’s, date the first edition 1973 — which puts it firmly inside US copyright either way. The 1963 Harvard Business Review article is likewise in copyright. The sentence is quoted here in brief for identification and commentary; it is not public domain.

Fact-check

What gets muddled

Putting Drucker’s name on this is not a mistake — he is the right man. But four separate things travel under his name, and none of them is his exact printed sentence — that is below.

Peter Drucker compressed

What Drucker printed in 1974 was “Efficiency is concerned with doing things right. Effectiveness is doing the right things.” The circulating one-liner deletes “is concerned with” and swaps the full stop for a semicolon. Quote Investigator ↗ titles its investigation with Drucker’s longer wording for exactly this reason.

Warren Bennis different author

“Management is doing things right; leadership is doing the right things” is a different saying with a different owner. Stephen R. Covey put that line in The Seven Habits of Highly Effective People (1989) and credited it to Drucker and Bennis jointly; Quote Investigator ↗ finds the evidence points to Bennis for the leading-versus-managing framing.

The Effective Executive (1967) undocumented

The quotation is routinely footnoted to Drucker’s 1967 book. Barry Popik ↗ writes only that Drucker “said something like this in 1960s lectures and in his book, The Effective Executive (1967)” — a hedge, not a page reference. The sources actually documented with text are the 1963 article, the 1965 lecture and the 1974 book.

an 1869 newspaper filler and columnist Elsie Robinson older

The right-thing/thing-right wordplay was in print long before management theory existed: an 1869 Harrisburg Telegraph item and a 1934 Elsie Robinson column both use it, as Quote Investigator ↗ documents. Drucker’s contribution was attaching it to the pair of business terms.

Drucker’s own sentence, verified against scans of the 1974 edition ↗, runs two words longer: “Efficiency is concerned with doing things right. Effectiveness is doing the right things.”

Context

Why it stuck

Drucker’s complaint in the May 1963 Harvard Business Review was not philosophical, it was practical: every tool a manager had — above all the accounting numbers — measured how well things were being done, and none of them asked whether those things were worth doing. The efficiency/effectiveness pairing was his way of naming the missing measurement.

The phrasing survives because of its shape. It is an antimetabole — the same words returned in reversed order — which is why it compresses so easily, and why it kept mutating: efficiency versus effectiveness, management versus leadership, CEO versus COO. Each generation of business writers reset the two nouns and kept the frame.

Efficiency is concerned with doing things right. Effectiveness is doing the right things.

Read the full story

In 1965 The Financial Post of Toronto printed a digest of a Drucker lecture at the University of Toronto in which he set the pair out at length, arguing that a business can die of inefficiency but that no business grows merely because it is efficient. Quote Investigator reproduces the passage.

The shortened phrasing was circulating well before the 1974 book. Barry Popik’s file records a September 1967 report in the Sunday Herald of Provo, Utah, in which Stephen R. Covey — then a university administrator, two decades before The Seven Habits — told students that “efficiency is doing things right and effectiveness is doing the right things.” No source is named in that report.

The true author

About Peter Drucker

Peter Drucker

1909–2005 · Austrian-American management consultant, educator and author

Peter Ferdinand Drucker was born in Vienna in 1909 and died in Claremont, California, in 2005. He is generally treated as the founder of modern management as a field of study, and his books — among them The Practice of Management, The Effective Executive and the vast 1974 textbook Management: Tasks, Responsibilities, Practices — introduced ideas now so absorbed into business language that they read as common sense. He described himself not as a management theorist but as a social ecologist, interested in how institutions shape the people inside them.
