This chapter ties DAS to five pillars and translates each into practice. Clinical experimentation: help before measurement; run tiny, context-specific interventions; replicate across settings; keep ethics and consent explicit. Pragmatism and abduction: start with the problem, treat hypotheses as prototypes, shuttle between ideals and constraints, and let emergent patterns guide the next design. Fine-grained blend of work+learn: small actions with fast feedback; protect a few minutes for reflection inside production; use the plan–act–feel–reflect cadence to keep learning continuous. The intrinsic value of deep reflection and feedback: write to think, mirror responses to deepen insight, reply within 48 hours, and keep a short quote bank as the organization’s collective memory. Written collegial learning via protocols: standardize assignment language, write down design principles, maintain shared libraries with version history, and anonymize when sharing beyond the group. The chapter avoids academic detours; instead, it shows how these ideas make DAS reliable, ethical, and scalable in messy environments. You’ll finish with a coherent mental model that links method choices to outcomes—and a toolkit to keep theory and practice reinforcing each other in every cycle.
