Paper Prototype (First Iteration)
< insert pics here! :) >
Briefing
Thanks for agreeing to help us out! What you see here is part of a project we’re working on for the User Interface Design class (6.813). Today, you’ll be helping us test a new system for keeping track of outsanding expenses among friends and acquaintances. This system, called PennyPincher, is a means of recording and monitoring transactions among individuals and groups. We’re testing particular parts of the system which allows you to post new transactions to declare that someone owes you money, dispute a transaction you think is incorrect, and view a history of all transactions you’ve been a part of.
Here’s how it’s going to work: We're going to present you with a paper prototype of the mobile web app, which is fairly rough representation of what the mobile site might look after we build it, but on a much larger scale. Depending on the type of mobile phone you are on, the stylus will be your mouse or your finger (for touchscreen phones). We'll give you a few short tasks and ask you to try to execute them on this "web app". As you click on things, We’ll physically change the website to respond to your actions. Let me briefly introduce you to our team. My name is __, and this is ___ and ___. After we get started I'll be controlling the "computer" and they're going to be taking notes to identify areas where we need to fix our system.
Also, keep in mind that we're testing the computer system and design, we're not testing you. The system is at an early stage of development and is likely to have problems that might make it hard to use, so we need your help to find those problems. Please feel free to think out loud to help us understand your thought process, too! Your test results will be completely confidential, and you can stop at any time you want. Do you have any questions we can answer before we begin?
Scenario Tasks
Task 1: Adding a transaction
(Version A)
You went to lunch with a friend, Joey, and since he was short cash, you had to foot the bill (which you have decided to split evenly).
You want to add a transaction that shows that Joey owes you.
(Version B)
You went to lunch with a couple of friends, Karen and John, and since they were both short of cash, you had to foot the bill (which you all have decided to split evenly).
You want to add a transaction that shows that Joey and Susie owe you.
(Version C)
You went to lunch with a couple of friends, Joey and Susie, and since they were both short of cash, you had to foot the bill. It came out to $60. Karen insists she pay $40 since she ordered a courmet entree. John just got a soda so he owes $5.
You want to add a SINGLE transaction that shows Karen and John owe you the correct amounts. (Note, you will be financially responsible for the remainder)
Task 2: Dispute a transaction
You believe that one of your friends, John, mistakenly thinks you owe money and has posted an incorrect $10 charge for lunch at UBurger, when in actuality, you've already payed him back.
You want to dispute the $10 transaction that John has made.
Task 3: View summary page and individual history
You want to see a full list of people with whom you have made transactions with. After, you want to view all of the transactions made with Adam.
