The brief
In order to improve their current Ultra plan, Plum was looking to offer users a new feature to drive engagement through gamification and boost retention. We came up with the ‘Naughty rule‘ concept - users deposit money every time they shop somewhere they’d rather not!

Research and user testing
We ran two types of user tests during the project, a round of user interviews asking a panel of users general questions about the current app, their needs and saving goals. The results helped us shape the new feature proposition. Following this, as the Product designer on this project, I was in charge of prototyping our first concept and testing the new Naughty rule feature with users. Our goal was to capture pain points, test usability as well popularity of the feature.
