Deliberate practice

Also known as: Deliberate practice (Ericsson)

German: Gezieltes Üben

In research on expertise, deliberate practice is effortful activity designed specifically to improve performance, usually with clear goals, immediate feedback and repetition at the edge of one’s ability; K. Anders Ericsson, Ralf Th. Krampe and Clemens Tesch-Römer introduced the concept in 1993.

In one sentence

Deliberate practice: effortful activity designed to improve performance, with goals and feedback — Ericsson, Krampe and Tesch-Römer (1993).

Example

Instead of writing one more procedure as usual, a writer rewrites the same procedure three times against a checklist of the errors found in the last usability test.

How it applies

  • The original study: Ericsson, Krampe and Tesch-Römer (1993) studied violinists at a Berlin music academy and found that the best students had accumulated more hours of solitary, goal-directed practice. They distinguished deliberate practice from work, play and mere repetition.
  • The debate: The popular “10,000-hour rule” came from later popular accounts, not from the study, and Ericsson rejected it as a rule. A meta-analysis by Brooke N. Macnamara, David Z. Hambrick and Frederick L. Oswald (2014) found that deliberate practice explained a substantial part of the differences in performance in games, music and sports, but not most of them, and much less in education and professions.
  • Working method: Deliberate practice is defined by its design — a goal, feedback and work at the edge of ability — not by the number of hours.

Deliberate practice vs. repetition

Repetition makes a behavior automatic (see habit formation). Deliberate practice works on what is not yet automatic and needs attention and feedback; it is effortful by design.

How to read this pool

Entries, context cards and transitional topics

The art of thinking explains ways of thinking — where a method comes from, what it asks of you and how it was adapted later. You meet four kinds of content here, each with its own job:

Glossary entry
Defines one concept or method of thinking: its origin, an example and how it relates to neighboring ideas. “X vs. Y” sections set two methods side by side.
Context card of the art of thinking
A short, self-contained answer to one question about a way of thinking — its lineage, its steps, its limits. These cards are listed on The art of thinking only.
Transitional topicBridges both pools
A context card that bridges both pools: it shows how a way of thinking was adapted into documentation, analysis or quality practice. It sits with the reference context cards and is marked as transitional wherever it appears.
Reference entry or context card
Belongs to the Glossary & Norms Space on regulation, norms and engineering. Entries here link to one only where a method is also an established tool of documentation or quality work, such as the five whys or a user’s mental model.
