# Case Study

## Overview

A good case study proves value through a real story. It is specific, credible, and focused on outcomes the reader cares about.

## When to Use

- Customer success stories
- Sales and proposal support
- Website or marketing content
- Internal examples of successful delivery

## Classic Structure

1. Customer / context overview
2. Challenge or problem
3. Solution / approach
4. Implementation highlights
5. Results and metrics
6. Quote or testimonial (when available)
7. Key takeaways

## Principles

- Focus on the customer’s world, not your internal process
- Use concrete numbers whenever possible
- Keep the narrative tight and scannable
- Make results believable (avoid vague superlatives)
- Obtain necessary approvals before publishing

## Verification

- [ ] Problem → solution → result logic is clear
- [ ] Outcomes are specific and credible
- [ ] The story is relevant to the intended audience
