The objective here was to pick a company with a digital product and help better their digital experience. Using Jakop Nielson’s Usability Hueristics, we were able to identifiy usability issues and then present a redesign.

As a user of the Green P app who struggled with its usability, I felt the need to propose this to my team members and they accepeted the challange! We began with evaluating the applicationg, noting the usability issues and then reading user reviews from the App Store, Play Store and Facebook. 

Heuristic
Evaluation

Aesthetics and minimalistic design
‍
1. Redundant text, “Location ID” is mentioned three times which includes two helper texts.
‍
2. Hierarchy issues with location ID & Mobile Pay Sign
‍
3. Terms and conditions included an extensive amount of text
‍
‍
Match between system and real world
‍
4. There is unfamiliar language being used the word “Citation” can be confusing to the audience
‍
‍
Recognition rather than recall
‍
5. Unclear instructions how to use the “Green sticker/logo”

User Reviews

Understanding what works prevents us from changing a design that users enjoyed and found useful. Furthermore, the reviews provided great insight in understanding the users needs and pain points that they had experienced. 

Redesign

The redesign provides a better solution that focuses on the needs of the users, usability and overall providing a plesant experience.

Original Design

1. Clear and consice intructions on how to use the “Location I.D sign.”
‍
2. Larger signage for real world identification.
‍
3. Terms & Conditions were added separately as an alert so that the user only has to read it once.
‍
4. Static disclaimer was replaced with actionable terms. 

Original Design

1. Emphasized visual map information so the user can clearly see the area of parking they are paying for.

Feedback and Insight

This project provided a great opportunity to work together as a group, learning about our strengths and how to use them to come up with a solution. After our presentation of the redesign, we received a lot of positive feedback towards future changes. It was crucial to clearly state the usability issues, how it can affect the users' experience and how the redesign makes the experience better.

On a personal note, I enjoyed completing this exercise as I got to work closer with my colleagues to further analyze usability issues, how to improve them and learning about the value of usability.

And the cherry on top, the enthusiasm we received from one of the audience members. She was a user of the GreenP app who experienced the struggle and we were the ones who understood the pain. She expressed how the redesign is much better and useful! Furthermore, validating our work.
