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.
