Three things I like about this methods library

1. It's based on the book "This is Service Design Doing", so you can go further in each method by reading the book, plus you have access to it both in digital form and in print.

2. Photos of the methods in use: for each method you'll see photos of how the methods are used in real-life, that can make method that seem pretty complex very easy to understand.

3. PDF of each method: you can download a PDF of each method easily.
