Eneco aims to be climate-neutral by 2035 and is taking numerous steps to achieve this goal. One of these steps is helping entrepreneurs make their business premises more sustainable, but how they can accomplish this was a big question mark. That's where Morrow came in, specifically me and two other colleagues, to solve this issue. First, we examined all the data that Eneco had previously gathered (with or without external parties), and then we conducted our own desk research. We created an initial current customer journey, which we improved through interviews with entrepreneurs. This customer journey served as the foundation for the rest of the project and our collaboration with Eneco. And through this we were able to show which pain points we had to tackle together with them. We decided to tackle this challenge further using design sprints, with sprint durations of up to 2 weeks (yes, a bit longer than usual, but the prototypes we created needed to be more high-fidelity). During these sprints, we worked on at least 2, sometimes 3, prototypes in collaboration with Eneco's expertise. In the same sprint, we also tested the prototypes using various methods. We carried the results forward to the next sprint, serving as the basis for new ideas. In between sprints we presented the interim results to the management team and other stakeholders (from Eneco), each of whom had their own opinions and ideas, which we also incorporated in the project. At the end of the project, we compiled an extensive report containing all our results.
