Abstract
A summary of the main points of discussion raised during the talks and their follow-up questions,as well as in the round table of the last day of the $α_s$ (2019) workshop, is presented. The discussions not only focused on particular issues affecting each one of the individual $α_s$ extractions, but also on the current PDG categorization of $α_s$ measurements and on the methods used to average them into a single $α_s$ ($m_Z$) value. Most of the listed points are open and sources of potential controversies, which we highlight here as one might expect that ongoing progress in the field will lead to their clarification and resolution.
