Improving Tickets feature experience

by Rayza Gaharza

What is feature? Tickets

A feature where you purchase MRT tickets to ride one station to another within the app. The ticket is a digital QR that will be scanned for the user access. The ticket is scanned before and after the trip on the MRT gate.

From the user or travellers POV, the features is quite clanky and unfinished. The tickets is useful when traveller forgot to bring Flash or E-money. There is room for improvement and high potential use case if the product is delivered with better experience.

In this study case will be evaluating the user experience and conduct a research based on the MRT Tickets feature.

Research Summary

User Journey

The user flow is quite straight to point. Some of the features are not needed and too many third party that is implied. The ticket feature is useable yet lacks failure on QR scan and confused user flow.

Lacks of Information

The information that are needed are inform in separate pages. Implementing on compact information will improve user understanding of the MRT and ticket feature.

Underwhelm Visual

The visual of MRT app does not represent visual identity of MRT Jakarta. Some of the visual are hard to identify and there is a lot of ads in the app, which confuse the user.

User Flow

pre

user to identify checkout

HMW

HMW help MAU CFD AN ANAK TONGKRONGAN

HMW help user to prioritize train arrival and tickets

What is the problem?

Separated!

Ticket Highlight

Visual Hierarchy

The information of train arrival and ticket is shown in different page section.

User have difficulty in identifying train arrival and tickets in the MRT app. While user are tend to check the app for train arrival and their tickets.

Why is this a priority?

Based on user testing, user goal upon opening the app is to check the ticket to scan on to enter the station. While opening the ticket take a couple steps and can be simplified.

The failure of this problem will make:

(1) The queue in MRT longer while user open the app

Visual Hierarchy

Using the visual as call to action, user will prioritize their attention towards different visual identification. The ticket feature is one of the most used function in the app, so it is good to prioritize in the homepage.

Current visual hierarchy lacks of information that imply in the homepage. Prioritizing ads and additional features from third party app.

To improve the effectivity of the homepage is to prioritize the primary feature and design the secondary feature that support the main function.

HMW help user to understand total time travel

What is the problem?

they do not have the information of knowing when will they arrive at their destination.

As user travel within the MRT There is an error where the information that is applied only the arrival of the train in the station.

Why is this a priority?

From the user testing that has conducted, user will benefits from arriving on time while they plan or travel. While they travel with the MRT they will know when and what station are they currently at.

Only Departure Time

Travel Timeline

Informative Graphic

Travel timeline will give user the current state of location (station) and time of arrival. The travel timeline will give user a better experience knowing when they will arrive comparing with other public transportation.

Intuitive and Fun

The failure of this problem will make:

(1) The user arrive late or not knowing when they will arrive.

(2) The user uses third party to search for the information.

With the travel timeline, we can apply identity of the MRT train traveling or accelerating in the timeline bar.

This feature will make user to came back and uses the app while traveling with the MRT. Which in the last version has not been implemented.

Visual Indicator

Color Differentiate

HMW help user to identify checkout ticket

What is the problem?

The current version of the app has , which is implemented with QR scan. The only difference they made is only in green small bar, which is hard to acknowledge.

Why is this a priority?

lack visual clarity of the checkout ticket

This lack of visual will make user confused and having difficulties while using the app or in travel. With this confusion will make the user to ignore the app and travel with flazz or e money instead.

The failure of this problem will make:

(1) User confused and difficult while using the app

(2) Unable to pass the MRT gate

(3) User to ignore the app and use different payment method

Better User Flow

The help of color differentiate or other visual indicator can help user acknowledge the difference of tap in and tap out. The initial color of the QR will still be black and white for the QR to scanned easily.

The user understanding where they got to one point on app is important. The current version of the app does not give a good user flow of the tapout QR scan. Making the user confused and frustrated.

The indicator of the ticket will be shown clearly if the user has already tap in and ride the train, and introduce new visual for tap out and arrive in the destination.

Bringing together diverse perspectives and skill sets, design collaboration can help ensure that the final product is functional, aesthetically pleasing, and userfriendly.

Base Story

Once upon a time, in a world not too different from our own, every person was born with a spark within them. This spark was a representation of their individuality, creativity, and spirit. It was said that the brighter the spark, the more vibrant and fulfilling a person's life would be.

However, as people went about their daily lives, they soon discovered that navigating the world around them could dull their spark. The stress and pressure of work, relationships, and societal expectations weighed heavy on their minds, causing their spark to flicker and fade.

For some, the loss of their spark was a slow and gradual process. They found themselves feeling less passionate about the things they once loved, struggling to find motivation and inspiration in their daily lives.

But, some people find out they could not to let their spark die out. They made an effort to slow down, connect with their passions and desires, and

Seek out the things that reignited their spark.

And in doing so, they discovered that their spark was not lost forever. Instead, it was simply waiting to be rekindled, waiting for them to give it the attention and care it needed to shine bright once more. o they continued on their journey, seeking to nurture their spark and live a life filled with purpose, passion, and joy. And in doing so, they proved that no matter how dull the world may become, the spark within us will always burn bright if we choose to keep it alive.
