Fast-moving teams often ship great products—until the people building them burn out, communication breaks down, or friction slows delivery to a crawl. In this talk, we explore the human layer of software engineering: the invisible work that keeps teams aligned, the communication gaps that sabotage progress, and the cultural patterns that determine whether developers thrive or quit. You’ll learn how to design “sustainable velocity” into teams using alignment rituals, expectation transparency, decision frameworks, and adaptive planning that protects both people and product quality. A practical, research-backed look at the habits of resilient engineering organizations.
