Service Design Blueprint
Often, we need to describe a great deal of information in a simple and easy to understand way – the forest and trees, all at once.
When designing a service with multiple touchpoints, multiple user types and an expectation that the service may change or grow over time it can be hard to encapsulate all of this information at once.
Take a look at Service Design Tools and their post on Service Design Blueprints, which has some helpful examples. They can be a helpful lens for taking many types of information and making it comprehensible. A more abstract (and very clear) explanation of this tool can be found here.
