A PM's leverage runs through the engineering team — you don't ship code, they do. Working effectively with engineers means giving them clarity and context, respecting their expertise, and building a partnership rather than a hand-off relationship.
What engineers need from a PM
✓ The WHY → context and goals, not just a task list
✓ CLEAR requirements → well-defined stories with acceptance criteria
✓ PRIORITIES → what matters most, so they can sequence sanely
✓ PROTECTION → shielding from churn, interruptions, and shifting goals
✓ FAST decisions → unblock them quickly when they have questions
