This chapter covers how to collaborate with key roles (PMs, designers, managers) and how to gain influence across teams.

Working Effectively with Product and Design

Great products​ emerge from close collaboration between engineering, product management, and design. Cross-functional collaboration with product managers (who own product strategy and roadmap) and designers (who own user experience and interface) is particularly critical for effective engineers. Yet sometimes engineers and PMs/designers can feel at odds—engineering wanting simplicity/​tech purity, PMs/design wanting more features or a pixel-perfect UI. Effective engineers bridge that gap. To do so, and to foster a strong partnership, effective engineers adopt several key practices:

Understand the “why” behind requirements.

Don’t just take a task from your ticket tracker and execute blindly. Ask your product manager what user problem a feature is solving, or what metric it aims to move.
