If Architectures Could Talk, They’d Quote Your Boss

Software architecture reflects how organizations communicate and make decisions. Failures stem from misaligned incentives, unclear ownership, and structural gaps—not technical flaws. Architects must design not just systems, but the conditions for systems to thrive, using platform thinking to reduce friction and foster autonomy.
