EXPERT TIP
Use 9-window tool and daisy map

There are countless methods for adding structure to the insights: Venn diagrams, mind maps, system maps,
cluster analyses, customer journeys, and so forth.
The 9-window tool is a simple method for analyzing potential application cases and customer needs. In so
doing, the product or service is more closely examined in the dimensions of “system” and “time.”
“System” refers to the structure of a product or service, including its entire environment. It invites you to
zoom in to the product/service (subsystem) or to consider the super system (zoom out).
In the dimension of “time,” we vary the temporal consideration and focus on what happened in the past or
might happen in the future. This approach helps us overcome barriers and see the product or digital service
from a different point of view.
