A mobile APP design for PTV (Public Transport of Victoria)


Like London Oyster, Sydney Opal, PTV is a public transport APP for Melbourne.

In 2012, the PTV app was first launched to provide information on public transport services, fares, tickets and initiatives.

In 2018, we have observed that the PTV app is not meeting users expectation and not on par with its’ rivalry apps due to bad user interface, inaccurate information and inconveniences.

Sohow might we improve the quality of users experience to retain, regain and encourage more public transport users to utilise PTV app, and at the same time, promote bike share and walking as alternatives?

Now let me tell you a story of how I made a positive difference to everyday commute in Melbourne — with the inspiration from Harry Potter.

My Role

I participated in every phase of the project with a team of 3, from research, synthesising, ideation, prototypes to testing and iterations.

I also kept track of the project’s progress, making sure everyone works on their interests while meeting the milestones.

I proposed to invite Harry Potter in our ideation, which was believed to be an effective strategy (more details shown in Ideation).

My Reflection

Choose tools accordingly and carefully. We spent longer time in creating personas than we had expected. At first we tried to use spectrum to depict each personas. However, it was time-consuming in our case as PTV had a wide variety of users. Then we recreated it base on the interviewees with a bit modifications. As a result, it turned out to be an efficient method.

Start from MVP and learn through testing. Although there may be lots of awesome ideas generated from ideation, it is important to prioritise the features and keep the development in a lean way.

Follow the design patterns. According to our research, most users had experience using Google Map. Users are more likely to digest things they are familiar with.
