How we approached the redesign
Discovery: user interviews of first time buyer and remortgage customers, stakeholder interviews, tech exploration, design ideation, user personas, journey flows. Usabaility testing of three different prototypes replicating a full mortage application.
Incubation: presenting research findings, design direction, project team and stakeholder insight, feedback, feature prioritisation and MPV scoping .
Product Development: worked in an agile manner discovering requirements and developing solutions through team collaboration.
Product delivery: Nationwide is launching the application. Feedback will be taken from end users to form and evolve the designs.
Our main approach to the design was to chunk the content. This refers to the process of taking individual pieces of information and grouping them into larger units. This makes shorter forms per page but the trade off is more page clicks. The decision after all our usability testing identified users preferred simple and shorter forms as their confidence grew using the applicationas. Shorter pages also means lower congitive load for our end users, enabling the application process to feel less daunting.
Nationwide Building Society Design System was used as it is our single source of truth for all the UI elements allow us to improve consistency across Nationwide's platforms, also save time and money.
The image above is a good an example of how we chunked the journeys content.
Pages of the journey were designed with the intent to resolve the challenge of customers inputting the wrong data on mortgage application, which is an issue with the old designs. The items on the page are optional and users can click to include an outgoing. They user progresses to an additional page with related questions, which they are then prompted to fill out. The user is then present with a summary of their data. This page is a good example of the types of illustrations added throughout the application to aid visual users and make the process feel friendlier.
