Overview
The Index of Questions and Methods serves as a resource for matching business challenges to appropriate discovery processes. It organizes research and experimental techniques across four categories based on whether you're exploring market or product dimensions.
Key Process
The framework recommends a four-step approach:
- Identify what needs to be learned
- Consult the index for relevant methods
- Select an approach suited to your circumstances
- Track progress using GLIDR (opens in new tab)'s Research & Experiments tools
