The notion of a thermal optimum persists There is an underlying assumption that the best thermal environment never needs to be noticed, and that once an objectively "comfortable" thermal environment has been provided, all of our thermal needs will have been met. The use of all of our extremely sophisticated environmental control systems is directed to this one end—to produce standard comfort zone conditions.

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.
