The document describes the design thinking process used to create an app called "Night's DD" that assigns a designated driver to groups of drinking college students. Through interviews, the designer found that students drink regularly but rely on others for transportation and no one wants to be the designated driver. Their solution was an app that allows groups to either randomly select a driver or factor in excuses like work schedules to determine the driver in a fair way. A physical prototype of the app was created to demonstrate how it would work.

1. HOW DESIGN THINKING
SOLVES THE PROBLEM:
WHO WILL BE THE
NIGHT’S DESIGNATED
DRIVER
BY: PETER LANWES

2. TARGET MARKET
Typically college students
between the ages of 18-22, or
anyone who goes out drinking
with a group of friends

3. THE
PROCESS
INTERVIEWS AND RESEARCH WHILE
REMAINING EMPATHETIC

4. INTERVIEWS
• Interviewed 15 Quinnipiac students
( several from each year) in person,
all who partake in drinking.
• Asked several questions regarding
their drinking habits and means of
transportation after the “pregame”

5. RESULTS
• Everyone who was interviewed drinks at least once a
week, however, most drink up to 3 times a week
• Students typically rely on shuttles, cabs, or Uber to get
them to their destination, however, for local destinations
students often use a Designated Driver (DD), typically for
the students 21+
• No one wants to be the designated driver, only do if they
have to
• Students think that it should be chosen randomly,
however, they also think that other factors should be
considered that justify them not being the DD
• Examples: Had work all day, drove last time, I’m meeting
someone tonight, etc.

6. RESEARCH
• Looked up several smart phone apps, used for drinking
purposes
Scenetap
StearClear
Drunk Dial No!
All drinking related apps have a very simplistic design to them, and are very easy
to use. All are designed for exactly 1 purpose

7. MY SOLUTION: THE APP, “NIGHT’S DD”

8. HOW IT WORKS
OPTION A: DECIDE RANDOMLY

9. HOW IT WORKS
OPTION B: USE FACTORS

10. CONTINUED: OPTION
B
• Driver with the
lowest score is
the Designated
Driver
• Birthdays and
“Already started
drinking”
factors
automatically
guarantees that
person isn’t the
driver

11. PROBLEM/SOLUTION
SUMMARY
• Students on average rely on a DD once a week
• No one likes to be the driver
• Students think they should be chosen randomly, but also
sometimes think other factors should be considered
• “Night’s DD” app can choose a driver randomly or take
factors into consideration
