Definition

Prompt engineering is the practice of designing instructions, context, and examples that guide an AI system toward a useful result.

01

Why Prompt Engineering matters at work

Prompt design affects model behavior, but prompts are only one part of a reliable system. Clear instructions, examples, structured outputs, relevant context, tool design, and evaluations work together.

02

A practical workplace example

Example

A reporting prompt defines the audience, required sections, allowed evidence, citation format, uncertainty behavior, and a JSON schema consumed by the next step.

03

What teams should evaluate

  1. 01

    Define the exact task, input, expected output, and acceptable failure rate before choosing a technique.

  2. 02

    Test with examples that represent the languages, formats, edge cases, and user groups present in the real workflow.

  3. 03

    Document where the concept stops being useful so teams do not treat a general capability as a guarantee for every use case.
