Having experience working in IKEA as a construction PM, I remembered that some in-store customers were frustrated by their journey, especially when they got lost. I came up with the idea that it would be nice if the IKEA mobile app had a navigation feature so that the users would never get lost inside a giant store.
Brainstorming
At first, I documented an existing user flow of interaction with the IKEA mobile app to see where the navigation feature could be integrated.
After defining possible points of integration, I updated the user flow and I sketched screens of the in-store navigation.
Users should have access to the in-store navigation right from the start of the app use. That's why I decided to create a shortcut button for the main screen (2 image, sketch #2)
Additionally to basic navigation, I thought of reflecting checked out items on an interactive map so that users could plan their self-collect route.

Prototype testing
For testing the proposed solution, I decided to try a moderated in-person method. I've assembled Steve Krug's mobile testing kit inspired by reading his book "Don't make me think"
8 out of 10 invited participants could participate: the major participants' criteria were familiarity with IKEA products and in-store shopping experience. The youngest participant was 25 years, and the eldest participant's age was 53.
Testing showed that all participants were confused by redesigned checkout screen, where users had to press on the order to proceed to a navigation feature. Also, some touch targets were smaller than 40x40 px, and participants struggled to tap them.
Iterating on the prototype, I added a secondary button to the checkout screen to make navigation to the order more prominent. Also, the secondary isn't competing with a primary "Continue shopping" button, so users can continue shopping without distractions.
