We use [http://en.wikipedia.org/wiki/Blueprint BluePrints] to capture ideas, features, requirements and design options for Sahana Eden components. These can either be a simple collection of rough ideas about features you need or formal documentation following our [wiki:BluePrint/Guidelines/Template BluePrint Template]. You can review our existing [wiki:BluePrint BluePrints] to contribute to one of these or create a new !BluePrint at [wiki:"BluePrint/<NameOfYourIdea/Feature/Requirement>" http://eden.sahanafoundation.org/wiki/BluePrint/<Name of your Idea / Feature / Requirement>].

This can start with a simple [http://en.wikipedia.org/wiki/User_story User Story] (or a full [http://en.wikipedia.org/wiki/Use_case Use Case]). These can be simple stories which describe how Sahana Eden could be used in different scenarios.

It can then be mocked-up using [http://webstyleguide.com/wsg3/10-forms-and-applications/4-design-process.html Wireframes] or other diagrams (a picture tells a thousand words), using tools like:
