Process Flow Chart

Initial Concepting

Define opportunity space: Based on the 2014 Parking Strategies Committee Report of University of Texas at Austin, UT had 52,000 students, 17,279 faculty and staff, 5,000 visitors and 15,800 parking spaces in the year of 2013, which means the potential user to parking space ratio is 4.8:1. In short words, UT has a severe parking situation. To solve the problem, UT now allows a max of four members to share a parking permit and carpool to the campus. However, based on our user research, few students know the existence of this policy and the major problem for them to take advantage of this policy, is to find a carpooler.

Based on the reasons above, we designed a carpool app called T.E.A.M. for the UT students to find a carpooler. For one thing, we can help students find a carpooler quickly and much more easily. For another thing, the app advertised UT’s carpool permit policy, which can raise UT’s profit. In general, the app help with the severe parking situation for UT, and help students save time and money on their way to school.

User Research

1st Round User Research

In order to accomplish our goal of this project, we conduct a survey and interviews. This survey collects both qualitative and quantitative data from our target users on how they think about the carpool, how likely they use carpool, and what kind of feature they want to see in the app.

Competitve Analysis

In order to better understand the features, organization and design, we did an assessment of the strengths and weaknesses of current and potential competitor applications with similar goal and functionalities. They are Uber, Zimride, and Pool My Ride. This analysis provides both an offensive and defensive strategic context to identify opportunities and threats.

competitive analysis


The total number of response we got by now is 43. We categorized our survey into five different topics: demographics, way to find carpooler, carpooler type, reward, and difficulty to find carpooler.

Tailoring Scope

After our initial pre-interview and survey, we narrowed the scope of our system by focusing on the most significant usage performed by students at UT. Since the students of UT are our primary users, we then conducted second interview and collected their inputs in order to find out more insight on usage model. In addition, we also cooperate UT’s current carpool policy in our system and apply the benefits including reserving carpool parking spaces, reducing parking permit fees and offering extra UT share pass.

2nd Round User Research

As we narrow down our topic to UT students, we conduct another interview focus on UT students. In this interview, we get qualitative data to determine features expected to be implemented on the app and tasks need to be completed by asking students with car or without car how much they spend on the travel, how likely they want to take/give a ride, how they would like to reward/share gas fee, how they like to find carpooler/driver and so on.

Iterative Design

We discussed and determined the initial blueprint. Then we began with paper prototypes, drafting out the chosen design idea, which was supposed to show a flow of the main functions of our website. We gathered usability feedback from usability testing and iterated 4 rounds of the prototype from the early sketch to hi-fidelity mockups. Each iteration, we refined our ideas and design based on feedbacks from the usability testing. Meanwhile along with the design, we also settled down the Content Mapping and Controlled Vocabulary .
