The redesign of the Danfoss component selection software was part of a consulting project between Johns Hopkins University and Danfoss. The project consisted of analyzing the current market for rooftops units and proposing a solution that would allow the company to increase its market share in the North American region. We studied market data and analyzed customer interviews where we identified a gap between the current software and the usual workflow of the users. Once this opportunity was identified, we made a prototype of the solution that we presented to the company's stakeholders who were quite satisfied with the proposal.
