Individual Project
Co-Express is an individual design project, aiming to solve a problem identified in the neighborhood - delivery picking in apartment. The final design solution is an Ipad interface where tenants can record checked package, and map the system information to physical packages, so to eliminate repetitive searching.
The App allows tenants to mark the packages they have checked, and assign each a unique color for quick recognization.
The system would send notification to package owner, and print a sticker in the same color to map with physical packages.
Tenants can choose to turn on or off package notifications.

Define Problem

What The User Has to Say

One of the complains of living in a 31-room apartment (more than 60 tenants), is that delivery men always stock everyone’s express packages behind the apartment door. Searching can take up to 5min each time.
1.The name on the label is small to read. Each express company uses different format.
2.One package is checked repetitively by different people.
3.Sometimes when one package is not picked immediately, it can be checked twice or more by a same person
5 people living in different apartments are interviewed. They reported the same issue, and some others shared needs in delivery picking.
People want to know when to start checking, as the delivery time reported online is always inaccurate.
Most interviewees mentioned they are willing to help roommates pick their packages if they see it.
When their hands are not available, instead of leaving all the packages for later, they choose to take as much as they can, and leave the rest for next time.

Competitive analysis

The Existing Design & The Missing Features

I compared existing settings of how people pick up deliveries.
1.People living in house have their own mailbox.
2.DHL box requires amount of space. usually one in a neighborhood. Take 5-10min walk from home.
3.Chinese deliverymen separate deliveries by marked names or phone numbers.

Design Process

Sketch. Storymap. Prototype


Make Packages Easy to Search

In the beginning of the design process, we were asked to sketch the pieces of idea to solve the problem. Then we brainstormed more ideas, developed 8 of them into storyboards.
We used storyboard to ask for advices from peers. I started having a clearer image of what is a desired solution to support the certain context, making the workflow more concrete into story map.

Later, I used QOC(Questions, options, criteria) analysis to help me focus on the important aspects while making critical design decisions.


Make It Real

Iteration 1:Wireframe
Iteration 2:Paper Prototype
Iteration 3:Initial Hi-fi
To make the interface intuitive to use, I made paper prototype and tested with people. It helped me understand how users interact with the interface, and improve my design.
While iterating in the prototyping phrase, I learnt three things:
1. Even though the features are brand new, I should draw designs from other Apps which users are familiar with, to make it intuitive to use.
2. Before users pick up their own package, to encourage them to do a favor for other tenants, the App should work without a hitch, and take very few time.
3. As color is used to identify packages, the App design itself should be simple, not taking up too much user cognition in colors.

The App allows user to choose the package owner, or by default send to all tenants living in the room print out a colored sticker with room number on it. Send SMS notification to the owner (and the roommates)

After picking the package, user can clean the status in the system

The App allows user to change message subscription, and add new tenants.
