There’s almost a million of parking spaces in Housing & Development Board (HDB) estates across Singapore. HDB has been relying on a legacy digital system that has not been iterated on for over a decade. Officers overseeing the parking infrastructure have been dissatisfied with the manual processes and unreliable user experience. With increasing demands on parking management and evolving technological capabilities, there was a clear need to modernize the system.

RESEARCH
From the evaluative research, I learned how satisfied participants were with the prototype. Additionally, identified the required changes to improve the experience. User testing revealed that 5 out of 5 participants were excited about new experiences. Here are the main takeaways:
Some participant mentioned that it would be helpful to see when the pages were last updated
It would be beneficial to have a more advanced map with search feature
Two participants suggested a flexible search function. For example, allowing users to search by postal code or keywords, such as a block number

I would advocate for implementing sprint-based work during the discovery stage to better manage workload and deadlines. Instead, we only adopted sprints once engineering investigation and implementation began.
One of the calculated risks I helped the team decide on was using an open-source design system instead of building our own. I partnered with an engineering lead to choose the most flexible and usable option for our project. This approach allowed us to focus on solving real officers' problems rather than reinventing standard components. The team's velocity improved significantly, though we occasionally had to work around the design system's limitations to meet specific requirements.
