An award-winning service app for a statewide water utility in 2020.
Timeframe: 1st phase: 4 weeks + 2nd phase: 4 weeks
Role: UX and UI designer

Client
TasWater is Tasmania's water and sewage utility and it's owned by Tasmania Local Government.
Problem statement
TasWater legacy work management app was causing major issues for their internal operations.
Due to the complexity and limitations of the app, field workers struggled to manage their daily tasks, leading to frustration, stress, and inefficiency in their daily operations. This also made it difficult for TasWater to track fieldwork.
As a result, this led to decreased productivity and created significant communication challenges within the company, directly impacting overall efficiency.

Unreliable mobile reception

Complex navigation
Time-consuming process to find job details.
Inconsistent design
Different design patterns across the app caused confusion.
Poor legibility

What makes this project special?
With a team of just three, we're incredibly proud of this project!
This is my very first start to finish Experience Design (UX) project. From user research to design, usability testing to quality assurance (QA) testing. I enjoyed every second of it.
Hearing feedback like ‘easy to use’ and ‘save time’ from the end-users means a lot to me as a designer.
I am so lucky to be part of this cool project. Huge thanks to my superstar Project Manager, Damo, who taught me a lot, especially how to be a great (and brave) consultant, and the coding whiz, Kranz who taught me how to work with a 'platform-first approach' during development.
Delivering a field service app for a statewide water utility that serves over 470,000 people, all under a tight deadline was a huge achievement for our small team.
