A practical guide to diagnosing and repairing common dysfunctions in software teams, focusing on systems and processes rather than individual blame. It presents concrete practices—hiring and onboarding, role clarity, effective meetings and 1:1s, code review and blameless postmortems, feedback and career conversations, and sensible metrics—to build trust, improve communication, and increase reliability and productivity as teams scale. The emphasis is on creating durable cultural and operational habits that prevent recurring problems and make collaboration predictable and resilient.
