# From Frame to Challenge

Five layers of platform epiphany

You will get to understand and then describe your platform in five distinct layers. The three centre layers hail from the excellent [TRIE framework](http://platformed.info/the-trie-framework-platforms/). Moving left-to-right across this trio expresses how [participants](/extras/glossary.md#platform-participant) will learn the platform; the reverse direction describes how the platform will be built, tested, and managed:

**Tip:** Reading up on [TRIE](http://platformed.info/the-trie-framework-platforms/) makes for an excellent:kissing\_heart:introduction to building platforms.

This manual adds the two outer layers to capture the outside-in and inside-out design perspectives, making it a true end-to-end process.

There is no prescribed order to traversing the layers—as long as you make sure to visit and align each layer. For a first time exercise, best stick to the same learning path as the platform's participants: from left to right, from [Frame](/position/frame.md) to Challenge...:point\_right:
