# 9. Case studies

#### <mark style="color:blue;">Chapter 9 overview:</mark>

{% hint style="info" %}
This chapter is for project managers, community engagement officers and language leads. It's also for any organization that is planning a **voice data collection project and wants to learn from teams who have already done one**.

In **each case study**, a partner organization **shares**:

* the context and language they worked in
* how they approached data collection
* the challenges they faced and how they dealt with them
* the lessons they learned along the way

Note: The case studies are **practical and based on real experience**. You don't need any technical skills.
