Module 01: What Microsoft Copilot Is
Lesson 01.5: How Copilot Uses Context
Lesson Promise
Understand why context quality drives Copilot answer quality.
Real-World Scenario
A learner gives a vague prompt and gets generic advice, then adds audience, source, constraints, and examples and gets useful work.
Core Concept
Context can include your prompt, selected text, uploaded files, open app content, meeting or email context, work data, web results, or agent knowledge depending on the experience.
The more clearly you define source boundaries, audience, goal, and output format, the easier it is to review the result.
Step-By-Step Workflow
- State the goal.
- Name the audience and situation.
- Provide or reference approved sources.
- Set format, tone, length, and constraints.
- Ask for assumptions and missing information.
- Verify output against source boundaries.

- Expecting Copilot to replace policy, expertise, or business accountability.
- Forgetting that context quality determines output quality.
