In this talk, I will share my experience as a designer in a B2B marketplace with an assistive matching algorithm used by expert Account managers. Starting with little previous knowledge, I will show the steps I took to build up my confidence and collaborate directly with Data Scientists, finding common ground. I will bring the design strategies we adopted and the iterative process, addressing themes like trust and user control. I will share how to apply these principles in interfaces for Artificial Intelligence enabled features that provide a transparent human interaction. The takeaway is that the designer can bridge a double gap: between what the user understands and what is happening; and the intentions of who creates the algorithm and the user. As a team, we were able to transform the product processes involving that algorithm by drawing a clear path to maintain a dialogue between the business, the data scientists, and the users. I will show in practice that where there are people and machines, there are interfaces and this is the designer's territory. I want this to be an inspiration for product people from all backgrounds to take part in the discussion and challenge assumptions.
