In a delivery app like LINE MAN Messenger, the most important aspect is addresses. To ensure a smooth user experience, the sender and recipient location fields should be emphasised on relevant screens. However, in the current design, these location buttons are styled similarly to the "Share delivery status via LINE" button.

To better visualise the delivery process, these fields could be connected with dotted lines or merged into one element with two inputs. In this topic, an A/B testing is conducted internally, with selected choice being both locations merged into one element (and the lines connecting between two inputs as a second choice). 

Icons can also be used to provide visual aid, while important elements such as the location selector should include explicit instructions to guide the user.

As a sub-service in the LINE MAN app, it's important for Messenger to align its interface design with other services such as LINE MAN Food or Mart for a cohesive user experience. Fortunately, LINE MAN has its own improved design systems, so implementation is the only remaining step.

Finally, Messenger currently only displays advertisements through pop-up notifications from Leanplum. To inform users about packages and promotions, graphical banners should also be added to the main Messenger interface.

We tried placing in the header, after key elements, and on the confirmation page as a final promotion call. After testing, these all placements worked without hindering the functionality of the service. Still, we need to have the header as a static Messenger banner and others as a dynamic (remotely updated) banners as the header will affect the overall appearance of the UI most.

Also, the banners should not be too distracting or intrusive. The priority of the redesign is to improve usability and satisfy users, who value better products over promotions and discounts.

The key elements of a Messenger delivery app are inputting addresses, adding options, reviewing orders, and tracking delivery progress. To ensure speed, the app should default to the last used location for senders, allowing them to simply select the recipient location and move on.

Next, users will be automatically taken to the next screen.  They can now see an estimate of the delivery cost with different options to choose from like round trips and vehicle types. And in the future, users will have the added benefits of extra insurance and faster delivery options so they can have more accurate estimation of the delivery prices.

In the next step of the ordering process, users will enter essential delivery information, such as delivery location and selected extras. Messenger will then provide a summary of the inputted information for review. Once all information is confirmed and payment is selected, the ordering process is complete. Users can then track the rider's location and await their delivery.

In the delivery tracking screen, they will be able to share delivery progress via unique URL. As this feature is the second priority of this project, it will be explained later on.

Well, currently pinning accurate location is... painful (pun intended)

Yes, pinning location is easy; but making it error-free is just cumbersome. To enable users more fluid experience, we will need some solutions for this challenge.

The "get address by phone number" feature streamlines the delivery process by allowing users to enter recipient's (or sender's) mobile phone number instead of manually entering their address. However, it's important to consider privacy concerns, as users may have multiple saved addresses in their address book and there may be potential for misuse if safeguards are not in place.

To address that, we will need to make a request from another users. The user receiving the delivery will receive a notification on their phone to verify and select their saved address or add a new one. Once verified, the order creator will receive a notification. For Messenger users without the LINE MAN app, a unique webpage (like the one above) can be used to confirm their preferred location. The order creator will be notified once confirmed.

The LINE MAN app should provide  suggestion to users in “Select delivery location” page and let users input location URLs from Apple Maps or Google Maps for added convenience. However, due to development limitations and potential iOS 16 clipboard permission prompts, users may need to manually paste location URLs instead of typing in addresses to find their destination.

To expand the functionality of "Share status via LINE," a practical solution is a shareable delivery tracking link accessible from both the LINE MAN app and browser. But implementing multiple delivery stops will definitely raises privacy and map display questions. This will require further exploration for a viable solution for this matter.
