As with many of our projects, we established a cross-functional delivery team alongside our BJSS colleagues, which included researchers, designers, developers, integration experts, Enterprise Agile delivery leads, business analysts, and software testers. We blended Design Thinking with Agile and Lean methodologies which was a huge benefit and made it possible to deliver the Minimum Viable Product (MVP) in just 36 business days.
Our initial research phase gave us a good understanding of users motivations, frustrations, needs and wants, as well as understanding their expectations of the future of this industry. This gave us valuable insights, such as that some users preferred to set their car to charge at very specific hours to save them money, sometimes determined by a late-night energy tariff. Other users were intimidated by the details required for creating schedules according to times and tariffs, and so would prefer to simply arrange for their car to be fully charged and ready to drive in the morning.
We collated and mapped our findings into current and ideal user journeys, and used them to inform the design of our initial wireframes. After turning these early wireframes into clickable prototypes, we tested two approaches to scheduling, as well as the layout of the app, with target customers. Users were introduced to a basic ‘charge me til’ version, for those simply wanting a full charge in the morning – and an ‘advanced’ version – for those with stricter charging requirements.
