Establishing the ethos based authority of Kim: she has worked in the big tech firms of Google and Apple where she made mistakes and now she dispenses valuable advice to other tech companies.
Should we believe that these companies are icons of successful HR?
Certainly Google positioned itself as possessing paradigm challenging HR practices. Last I heard, Google wants to unlock the creativity of their employees by helping them balance their lives (life enriching programming) and giving them time to explore what they think is a best course of action (80/20). But the value of those practices are contingent on an individual's agreement with a company mission. Missions which can become complicated by various managerial interpretations. Thus, as workers, we are first asked whether we accept the interpretation of the mission by our manager(s) then we are asked to become the best we can in that shared understanding of the mission.
