Certificate of Deposit (CD) Selector

The Challenge

Certificate of Deposit accounts have adjustable rates that a user can select. The CD selector needed to be easy to understand, clear about feedback, and quick to use.

My Role

I worked with the design director to prototype and test several version of the CD selector. I created prototypes and the user studies to check them against. I also built out the component and content documentation.

Process

I worked on initial concept ideation through prototyping. We created user tests to compare different ideas.

Discovery

The Certificate of Deposit selector tool's design developed out of three principles. First: The minimum opening balance is $10,000 (or $25,000 for a specific rate). Second: The bank may offer up to three special rates at any one time. Third: All rates and their respective term must be selectable. We used existing client data to understand current CD account. From these we created a few designs emphasizing the most used amounts and rates. A requirement to allow the rates to be updated by the bank at anytime was added. We tested three designs of the CD selector for large and mobile displays to get to what is available today.

Result

Full documentation of interactions, content, and visual design were created for development.
