While working on the aspect of the object I also do need to work on the application. I divided intro different parts and followed this process:

1. Listing all the objectives user can or must achieve on sticky notes
2. Creating groups of objectives by gathering the notes
3. With these groups, creating screens or linked screens
4. Organizing notes to create a user journey
5. Directly adding notes and rough to add features on the screens
6. Using Lucidchart to create the user journey [from the purchase to the use of the app] and the technical journey

I consider this as the first prototype of the app. Now I should add more details about the different steps and create a rapid interactive prototype to test the link between screens and if users find it clear.

I’m using sticky notes to make the user journey and list goals.

I use Lucidchart to make it interactive and to share it.
