You may be familiar with customer journey mapping, which is a tool that allows stakeholders to better understand customer interactions with their product or service over time. The service blueprint contains the customer journey as well as all of the interactions that make that journey possible.
Because of this, service blueprints can be used to better deliver a successful customer experience. Think of it this way: you can look at a building, and you can read a description, but to build the building you need more than an image or description. You need the instructions – the blueprint.
