The correct answer is D, Concrete. Training from the Back of the Room uses the 4C model: Connections, Concepts, Concrete Practice, and Conclusions. The purpose of this model is to design learning so that participants are actively engaged, connect new information to existing experience, practice the concepts, and leave with meaningful conclusions or commitments. In DevOps leadership, this matters because transformation requires learning, unlearning, and behavior change across the organization.
“Concrete” appears in the model as Concrete Practice. This is the stage where learners apply new concepts in a realistic or practical way rather than simply listening to information. For DevOps adoption, this supports experiential learning: teams do not become effective by hearing slogans about collaboration, flow, automation, or feedback; they improve by applying those ideas to real work.
Curiosity, courage, and candor are useful leadership and cultural attributes, but they are not one of the formal 4C elements in Training from the Back of the Room.
