Viability, usablity, feasibility In an empowered product team, the product manager is explicitly responsible for ensuring value and viability; the designer is responsible for ensuring usability; and the tech lead is responsible for ensuring feasibility. The team does this by truly collaborating in an intense, give and take, in order to discover a solution that work for all of us. However, in a feature team, you still (hopefully) have a designer to ensure usability, and you have engineers to ensure feasibility, but, and this is critical to understand: the value and business viability are the responsibility of the stakeholder or executive that requested the feature on the roadmap.
